Victimhood is an addiction. Their dopamine rush comes in when people defend them. So they take no responsibility for their actions and behave in a way to invite hate or bullying justifing it as just being true to themselves. They rejected the idea of self filtering that is normal for healthy social interaction. They get off on being hated because that means "I'm jus being me! They are evil and hateful and I am righteous!" Then they invite so much bullying that eventually someone will be duped into defending them and so give him his fix.
