He also says the only way for humanity to be redeemed is if this society was destroyed and replaced with more primitive society

I absolutely agree with that.

So how can we destroy modern society and make a better world for incels?

There is only one way, which is ironically, quitting society and waiting. Look how the situation was like 3 years ago, look how was it 5 years ago and look how is it now, aside from inceldom. Lefties are going insane with their globohomogendero propaganda, more and more people fail into it, more and more people are depressed plus more and more men are alone because they can't find/ don't want to find foids. World is going downhill and the collapse will happen in few, either by sexual dolls revolution or AI - I will not see a reason to interact with outer world if this will come true.

And this will destroy normies and make it better for us. As hard it is - that's our only way.
