Even in countries where there is hate speech, what and what doesn't constitute it is normally broad, subjective and is frequently misused by state to prosecute people that have no ill intent.
The most egregious example is the Chelseas Rusell case in the UK:

Also not only that but it doesn't work. If you stop people from saying certain words they just end up making new ones to get around your censorship. It is already happening online, people will make up new words to get around any speech censorship e.g. "jogger" means black criminal and I will leave it up to you to work out what that is being used in place of.
Also banning certain words doesn't take into account regional dialect e.g. Faggot is a regional dish in England. They recently banned google ads for a restaurant that sold "Fanny's Faggots".

Or this curious case that I just found while looking for the previous one:

Hate speech legislation doesn't work and just causes people to start resenting law enforcement and have less respect generally for the laws of the land.
