It is a very grey area
That if you ban political parties, or ban people from being members of them, then you are compromising the idea of a democracy.

I respect the right of others to have beliefs that I disagree with, it's part and parcel of human life.

BUT (and this is a big but), when those beliefs include preaching hatred of others for racial reasons, general bigotry and intolerance and the incitement of violence, I reserve my right to say that their opinions are wrong. And that they are wrong for holding those beliefs. I also reserve my right to kick the living shit out of them.
