That's big part of the reason why all the genuine alt-right organizations and parties started to lose political capital in the late-2010s/early-2020s... New movements, same old lack of cohesion, same old lack of solutions to the problem of infighting the left has been notorious for over a century.
The Left was able to unite and keep the infighting to a minimum. A feminist will defend a Marxist, a Marxist will defend someone from the LGBTQ community, the Leftist media will defend the feminists, and so on. The Right lacks that cohesive unity the SJW left had during the Culture War. There's a reason why the Right worships Trump like a god so much. He's the one thing uniting them and keeping them from losing. The moment he croaks, it's over. The fiscally conservative people who like porn and free trade, the Culture warriors who want to focus on SJWs, and the religious conservatives who want a Christian theocracy, they will all tear each other apart, and the Left will come back to power.
The main difference IMHO is that the left can when pushed rally behind shared adversity and fight over the spoils later. The right is so in love with purity testing their own movements they lose sight of their goals and would rather let the world burn before tolerating an ally of convenience
And that's the problem. Friends don't grow on trees. The New Right feels free to alienate old allies just so long as they stay in power. They don't care right now, because their guy is in power, but once that ends, it'll fuck them right in the ass. If the Right isn't careful, they'll lose everything again like they did in 2020. Except unlike Biden, who was willing to treat Trump with kid gloves and even throw him a bone by giving him a weak opponent like Kamala Harris, the next Leftie president is going to want revenge. And he or she will use all the powers Trump claimed for the Presidency.
Razorfist, of all people, should know this game by now. He made a video about the EA-BF2 online gambling scandal where he pointed out that getting the government involved, even in a matter that sounds beneficial, will increase government power and the threat they can pose to civil liberties. The political and surveillance system Bush Jr. created to fight terrorism was used by Obama against far-right people. It stands to reason that all the powers Trump claims for the Presidency will also be used by a Left-wing president for Leftist goals. After all, if there's one universal rule for politics, it's "no backsies". What's OK for one political party is OK for all.
Hell, just imagine the American Left negotiating with the EU to create a prison for politically radical people they deem to be a threat to society. The Europeans start tossing far-right people into it, then a Leftist president wins the election in the USA and starts sending agents out to search the country and round up "troublesome" right-wingers to be deported from the country and tossed into this prison as well. Razorfist would burn with anger if that happened, but he's openly celebrating Trump doing the same to immigrants with CECOT.
