Hmm. All right, so here's how I'm looking at things.
Step One, Classification: Everybody gets classified innately as a part of how society operates. The second "Democrat" and "Republican" existed as labels was the moment that this happened. The big thing about this step is that there must not exist a cultural connection between the two. So if you hear rhetoric about one group being "un" or "anti" American for vaguely defined reasons, watch out, but we're not at the point where this could credibly be considered a step toward genocide. The 2016 (and 2020) election(s) were definitely caustic, but we haven't hit this point.
Step Two, Symbolization: See above. The closest thing I can think of for this would be the creation/implementation of vaccine cards, but you could also argue the same thing about social security numbers or, say, needing to make an account to discuss something on an online forum. Much like step one, there's a lot to be concerned about when it comes to people applying this vaguely. Just because you're unpopular doesn't mean you're being dehumanized in a way that would promote genocide.
Step Three, Discrimination: This hasn't happened at a national level. You're still capable of petitioning the government for a redress of grievances, and while some political actors have more of a claim than others (I'm thinking of Russell Greer's PAC here), I'm not seeing anything explicitly barring conservatives from seeking protection from discrimination. (You may also want to rethink this considering how a majority of the highest court in the land identifies as conservative.)
Step Four, Dehumanization: I've heard this argued about "soy boys" and "antifa" before. I'd argue that this is a sign of unfortunate political polarization rather than an attempt to create concentration camps.
Step Five, Organization: The stuff we're seeing with section 230 and Facebook is worrying! However, it's worrying in a very different way from what genocide entails. Gregory H Stanton's
writings on the subject are particularly illuminating here:
When I read this, I think about the
Muslim Surveillance Program before I think about anything more contemporary. (Although evidently Tucker Carlson's claiming that the government did something with regards to his recent encounter with a heckler? Does anybody have more information on that?) Yes, Facebook and Twitter are private companies who censor voices and are subject to political whims, and that's a problem we should confront sooner rather than later, but they aren't complicit in any domestic genocidal acts.
Step Six, Polarization: This inarguably is happening in the United States. Anybody who claims it isn't is lying to you or trying to sell something to you, and probably deserves their own thread if they double down on it enough. But it's not happening in line with explicit, nationally directed attempts to exterminate populations. And wouldn't this be easy now? Just withhold vaccines and medical support from red states.
Heck, this has arguably already happened!
Step Seven, Preparation: I haven't seen President Biden call for a final solution to the conservative problem yet, and I'm sure Senator Manchin wouldn't be an ardent supporter.
And evidently we're not at steps eight through ten yet so I'll stop at seven. The thing is, with some of the steps leading up to genocide, they're bits and pieces of what we consider inherent to our modern system. Nobody's demanding that we stop calling ourselves Republicans or Democrats because that might lead to genocide. Everybody's supposed to get a driver's license, that doesn't symbolize anything. And fiery political attacks against the other major political wing are bog standard for all politicians. I understand that we live in frightening times. It's good to have a community that will support and protect you, inarguably so. But while polarization has hit a point where some of us are considering violence against one another, it's nowhere near as bad as conditions in, say, Rwanda circa 1994 or Germany circa 1941. It's important to see the parallels and do our part to prevent things from getting that bad, and only by understanding what happened and how things developed can we uphold our promises to never forget and to never again another genocide and/or Holocaust to occur.
