>is that the other side will do it anyway and you end up dead.

Preemptive first strike logic[1] aside. This logic doesn't work because political violence never gets out of hand so fast that an entire political movement can be wiped out. On the other hand by starting/advocating for political violence you're almost certainly going to get the descent into sectarian violence before you can wipe out all the "fascists".

[1] Iran, anyone?

> political violence where it is warranted

When is it warranted against you?

Let me guess, it never is because “your side” is never wrong and always “the good people”… right?

What an amazing coincidence!
