We cannot afford to put restrictions on speech, even if what we’re restricting is bad.

If we stop anything because it is hate speech then we are stopping any speech, because any speech could be regarded as hate speech if looked upon from a certain point of view. You can always justify why you believe some speech is hate, you can always find a way to make anything that anyone says look like hate speech, and you can always get away with it, and find countless other people who agree with you about such views. If we stop making people say what they want because someone else might get or be offended or because someone else might consider what these people are saying to be hate speech, then we will never have freedom of speech. We have to be allowed to speak freely about anything. Placing any restrictions on what we say because it might offend someone, because of political correctness, or because of fear of saying something that could be considered as hate speech or is actually hate speech, will only annihilate our right to freedom of speech gradually until there’s nothing left of it. If we start saying people are free to say what they want with only a few exceptions, then you are not free to say what you want. Even if these exceptions to what you are allowed to say do not increase over time, still the very existence of one exception to what you can say will mean that you still do not have absolute freedom of speech.
