In order to believe in freedom and democracy you have to be willing to accept defeat for while.
For what you get with democracy isn't the right to win, but the right to stay in the game even when you lose.
In practical terms, that means were only allowed to battle against (for example) the KKK. We aren't allowed to muzzle or outlaw them. They always get to come back tommorow and have another go at us. Democracy rejects ultimate victory no matter how worthwhile the cause. This is the great sacrifice democracy demands. Whenever you hear about proposed restraints on politically provocative speech its usually rootied in an unwillingness by the proposer to make that sacrifice. The fantasy is that they can have democracy and simultaneously deny the offending party their chance to win.
