No it's not. It's literally any faction with hardline dogmatic views. An extremist faction that manage to kill all their opponents doesn't suddenly become non-extremist when they're the new majority.

I have seen the arguments for "why it's positive for them" and they're bullshit. They're using it to justify racism and corruption and to defend politicians on their own side that even break the law (like a certain raid of a certain meeting concerning classified information).

I'm open to actual evidence, not just mere statements of disbelief. Can you provide counterevidence?
