If you refer to peaceful methods, then look no further than Ghandi and MLK. Protest peacefully. Make them raise their fist. And record it, tell the stories, reduce their mandate.
If you come from Malcolm X's or IRA's point of view: assassinations, military-like strikes, and generally war.
I reserve judgement on which way is better.
Gandhi was most effective when the Indian armed forces rebelled.
MLK had Malcom X.
You need a good cop and a bad cop.
If you can see some compassion or love in your enemy's eyes, then every time they hold up their fist to beat you you should hold up a mirror.
Of course, we're assuming asymmetric warfare here. No-one honestly believes FDR was wrong to declare war on Japan.
"Where is the line" for how much we should "tolerate intolerance" is a very easy question to answer.
The line is at current, US law. Break the law with your intolerance, via engaging in violent assault, and you should go to jail.
