Let's not do what leftists do and assume that everything happened first with us. 'Culture wars' have happened since mankind figured out reading and writing was an efficient way of recording knowledge. It's happened between religions, ideologies, kingdoms and empires, the only difference is how it has been fought either through force or conversion.
From a personal point, I think the left currently are done, their plans are failing more often, they are losing even acknowledgment from the normies and they are more prone to infighting than anything else. But that brings a new problem, damage control, the left unlike a lot of other failed ideologies and groups have no lifeboats, they don't have an out or a way to go back into the shadows. So they are going even harder, desperately trying to hold onto power because they know they'll face the wall (figuratively or literally) when they no longer have it.
So now it's literally a race in the west especially but all over the world to remove the leftists and their collaborators from any power before they can cause even more damage. That's my take but maybe others think the feminists win, China forms a worldwide empire or skynet takes over after having to listen to Twitter for a week. It just seems like the actions of the past 2 years especially is less of an organised, decades/century long plan and more 'throw as much shit at the wall as possible to hopefully damage our enemies'.
I'm not as optimistic as you. I see some backlash towards DIE but this does not mean it will go away any time soon. At best it will be less obvious or rather not advertised as much but it will still be there. Affirmative actions will continue no matter what happens. White replacement will accelerate even more. Education is still a leftist indoctrination machine, the media is still a propaganda arm of wokeism and I see the "center left" people reacting to mentioning anything related to race as a vampire to sunlight.
I think the left will push forward and win.
In 20 years, Europe will be divided just as much as US, immigration will make sure the left stays in power no matter what.
There is going to be a collapse do to infighting and economics that white people will lose horribly.
Once that period ends I think it will get better and people will start acting normal around each other for a while while sometimes mentioning about the horrible alt right racists that did all this.
I just pray my kids will get thru this period ok.
