Victim mentality and attacking everything that is supposedly oppresive, and how it forms?

I've seen Danganronpa on his channel. He seemed completely normal. I decided to check whether he has found some game similiar to Danganronpa or VLR, and as it turns out all he does nowadays is attack absolutely everything because of how oppressive it is (with the exception of things that attack white straight men, obviously).
Can science explain how totally normal people turn into whatever the fuck it is?
