In my mind it goes down to this: if your behaviour and ideas go against other people and cause harm (like being a racist, homophobe, xenophobe, anti feminist piece of shit), then it's not a valid opinion, it's a menace for society.

I get it, everyone has the freedom to express themselves. But that doesn't mean you are right or valid. So ok, they can say whatever they want. I'll just block the hell out of anyone who's like what I mentioned above.

I would put up explicit rules for that if it were my site... but as I said, it isn't, so I'll just have to go with it.
