One way to think about rhetoric like this is that it serves as a method of forcing you to align with their view of reality. Either you agree with them, or they paint you into a corner that then frequently creates a hostile response. In other words, they aren't looking for a discussion. They're looking for a fight.
That kind of nuclear option rhetoric wise allows them to feel empowered both by denouncing an enemy and creating a call to arms within themselves and others. Furthermore, even if it antagonizes you, it draws you into their struggle, which legitimizes their world view. It creates a threat for them to fight against. If their rhetoric causes someone to radicalize to the other side, even better. It just strengthens the immediacy of their cause.
This is how Antifa and Neo-Nazis can have a weird kind of symbiotic relationship. Even if their methods don't recruit someone to their cause, forcing that person to become a part of the overall struggle legitimizes their world view, strengthening both parties at the same time.
