Is it normal i don't think "hate speech" should be illegal
I don't. I think it's important to hear the un-filtered filth people want to say, so we can recognise and challenge bad ideas when they appear. The only exception I would make is when it's literally verging on threats and physical violence.
I think banning hate speech is a slippery slope. It's bad when you have potentially harmful ideas masquerading as "identities", such as religious identity, which can't be questioned or it's "hatred".
As a gay man, thank goodness America does not block The Westboro Baptist Church's free speech. Why? Because people see what they're saying, see how extreme it is and are rightly disgusted by it. Hearing their zeal and bigotry has (partly and indirectly) helped some people become supportive for LGBT people.
It also works in the other direction. People are seeing the outright lies, victim mentality, double standards and racism of low expectations that the SJW extreme far-Left has, and there's massive resistance rising against that too.
It's important to keep the balance in society to allow ALL speech, perhaps short of literally calling for violence.
