Meh, if I was going to be a Pagan, I'd rather go for Hellenism and worship the Greco-Roman pantheons instead of LARP'ing as a pathetic Nordic or Celtic yokel who lives in a cave and shits in the woods.
Varg Vikernes and his Nazi Viking LARP'ers are fucking stupid, but to their credit, they are nowhere near as autistic and cringe-inducing as Wicca or Satanism.
I mean, I get why so many white Americans are drawn to Paganism, whether it be the few genuine attempts at reconstructing European polytheism, Nazi Viking LARP, or whiny Wiccan SJW bullshit. It's mainly because of the failure of American Protestantism (especially the Evangelical wing of it)
American Catholics and mainline Protestants (Lutherans, Presbyterians, Episcopalians) have pretty much stopped being devout and are mainly Christian due to cultural inertia, and generally only attend church on Christmas, Easter, or during something like a wedding or funeral.
The only genuinely faithful Christian communities in North America left are Catholic and Eastern Orthodox immigrants (and the first generation of children raised by them) or insane redneck Evangelicals who are basically modern-day Puritans.
There's also a fair degree of genuine faith among "third-party" Christian groups like Mormons, Jehovah's Witnesses, Seventh-Day Adventists, the Armstrong churches, and the like, but they are all fairly small and aren't as culturally visible as Catholics or Protestants, with only the Mormons having any real cultural impact in America (mainly in Utah and other Western states with a high Mormon population)
For most suburban Americans, Protestant Christianity is either associated with stuffy older folks who don't even believe and mainly attend church for social appearances (same applies to most American Catholics), or they associate it with the right-wing Evangelicals, and it's the latter group that led to the rise of Atheism, Paganism, and groups like the SJW's and Alt-Right among Millennials.
The Evangelical Christian movement are generally tied into some real hardcore autistic nonsense like Young Earth Creationism, old-school homophobia, shitty Christian Rock, and trying to ban stuff like Halloween, rock music. D&D, and anything that was remotely sexually suggestive in media. typically with no real justification outside their fanatical interpretation of the Bible, mainly due to the high visibility of the fundamentalist wing of this movement.
The Evangelical movement (or at least the fundies within it) were the main fun-hating moral guardians in the 1980's and 1990's before the SJW's came along and essentially replaced them as the moral authoritarians.
Tellingly, the majority of Millennial folks were kids and teenagers during the Religious Right's heyday in the 80's, 90's, and early 2000's. That's why I think so many Millennials are hostile to anything connected to Christianity.
To them, Christianity in their minds is either faithless socialites and pedophile priests, or it's people like Jack Chick, Jerry Falwell, Pat Robertson, Kent Hovind, and the Westboro Baptist Church.
Naturally, these kids rebelled in their teen years and due to a distorted economy and broken education system, most of the Millennial generation never really outgrew their rebellious teenage phase.
So the majority of Millennials are typically atheists, both the fedora-wearing "M'lady" types and the SJW dangerhairs and soyboys found in communities like ANTIFA/Neo-Communists and Atheism+
The majority of the American Millennials who are not atheists are usually some brand of Neo-Paganism, with the largest groups in those movements being Wicca and Norse Heathenry, the former being an SJW magnet and the latter being an Alt-Right magnet. Cathy Brennan is an example of a leftist pagan lunatic while Varg Vikernes is an example of a right-wing pagan lunatic, and tellingly Brennan is a Wiccan while Varg is a Norse heathen.
While a lot of Wiccans and Norse Pagans aren't SJW's or White Nationalists (and those who aren't detest the ones who are), it's mostly the Boomer and Gen X adherents of these religious movements that reject the Identity Politics elements that have infested these groups.
Wicca was probably more infested with political nonsense due to being the largest of the Neo-Pagan movements in North America and as such, was more visible and accessible to a lot more people.
The general emphasis of female empowerment and respect for nature in the various forms of Wicca were a draw for a lot of SJW's and proto-SJW's, as was the fact that Wicca in America was largely tied to the hippies throughout the 1960's and 1970's.
Norse Paganism in America has been documented since the mid-1970's, but it was smaller than Wicca and was largely a fringe movement within a fringe movement (similar to Hellenic polytheism today) and the more genuine attempts at Neo-Pagan polytheism in the 1980's and 1990's were mostly inspired by and dominated by Celtic traditions, with the Druid movement being the driving force in that wing of Paganism, starting with Druid societies that started as college fraternities in the 1950's and 1960's (and were largely tied to Wicca and Victorian Romanticism) before truly trying to develop a more genuine identity in the late 1970's and 1980's.
Before the late 2000's and early 2010's, the majority of the few American Norse heathens were not really into White Nationalism, with David Lane and the Wotanist movement being the only real main exception, and most of his followers were tied to prison gangs, which limited his influence outside of the correctional system.
Also, David Lane was originally involved with Christian Identity (AKA "We Wuz Kangz" for white people) for years until he went to prison for the Alan Berg murders. Combined with his incarceration, that really damaged his reputation and influence among the Neo-Pagan community outside of prison.
Norse Neo-Paganism really exploded in popularity during the 2000's and 2010's, mainly because of the infamy of Varg Vikernes and the wave of Neo-Nazi Viking LARP'ers he inspired as a result.
You had a bunch of Alt-Right Norse Pagans enter the fray, but the increased visibility also inspired a non-racist element of the movement that was more in line with the smaller pre-Varg Norse heathens from before, often with an interest in historical reenactment, HEMA, and the like.
Really, the rapid growth of Neo-Pagans in America wouldn't have happened had the Religious Right not been so loud and prevalent in American politics and media during the 80's and 90's.
TL;DR-Nazi Paganism is utter bullshit, but so are most forms of Neo-Paganism, aside from maybe the Druids and Hellenics, since they're largely apolitical history geeks.
