There is danger too. Normalizing the speech also makes the actions seem less abnormal. Lets use PDP’s choice. If it is not ok to say “Kill All the Jews” then is is obviously not ok to actually kill them. But if it is ok to say it, you are one step closer to normalizing the actual harm. It works in less dramatic ways. Using the other example, if it is not acceptable to call someone a “faggot” they are also less likely to be beaten up for being gay in that environment as well. Hate speech has an effect of dehumanizing a person or group, which makes them fair play for harm.
