I think there's going to be an argument from someone on this but oh well.
People want to silence hate speech because majority doesn't agree and thinks it's wrong, I get it. But rather than silencing them which will ultimately change nothing..why no offer an open dialogue about it. No one said you have to agree with the things they say, but they don't have to agree with you either. It may not be right for them to say the things they say, but to have the authority to just bang down the hammer and silence someone? What's that solving? It's the same as sticking your fingers in your ears and not listening ... But they're still there. You don't have to associate yourself with them nor engage with them..I just don't think you should have the right to silence anyone. If they're ignorant enough they won't have many people listening anyways.
