Define exactly what is "hate speech"? If one sincerely believes homosexuality is morally wrong, and truly believes that the have a homosexual person will go to hell if they don't repent, is that hate speech? If some on beleves abortion is truly murder murder, is I hate speech to express those views?
If someoGivenbias or and intolerance of those of the left for any views but their own, unless hate speech is very carefully and specifically defined, it will just be a tool to allow people to supress views they don't agree with. Climate Change spektics will be accused of hate speech, no doubt.
And banning the speech does not make those ideas and sentiments disappear, it just drives them underground. Unpleasant as it is, it is better that I in the open, where the hey can be combated and debated, and the flaws in the claims exposed. True, most of the people holding these ideas won't changge overnight, but overtime you might be surprised, KKK members have been known to change their views. We can demand that derogatory and offensive language be banned, and that appappl s to the left as well as the he right, but unless we allow people to express their opinions, how can we know what they are truly thinking, and address our arguments to those concerns?
