Recently Twitter banned Milo Yiannopoulos and there has been much uproar. It seems Twitter has taken a stance (which they have a right to, by the way). I think there does come a point where one should not be able get away with saying anything and not face the consequences. 

There is the argument of Free Speech, which only means one is allowed to say what one wants, but does not mean calling someone names and not expecting to be punched in the face. Also on the other hand, as much as it is free speech for share the opinions, it is also the right for the other person to be hurt (and it is NOT a right to hurt another person). 

I think XKCD comic captures it perfectly.
