Culturally, we need to get to a place where words aren't considered a form of violence, and where mere discussion of controversial ideas isn't shot down for "giving the enemy a platform." The concept of a calm debate really needs to make a comeback.
"It is the mark of an educated mind to entertain a thought without accepting it."
- Aristotle (paraphrased)
In any case, I’m talking more about the cultural value of politeness and free expression of ideas, which almost by definition would exclude any extreme sort of hate speech.
