You seem to have trouble understanding the bigger picture, or you're really stupid enough to think that Trump is going to make things better for these people. Let me fix this for you:

"you are an incel because of your actions" > they are and get offended and vote trump > Trump wins > things for them go from bad to much worse

So when things get even worse for them under Trump, they have no one to blame but themselves, and certainly not random people on the internet that they feel offended by.
