People seem to forget this

Amen my brother! Or sister as the case may be.

Precisely. Nowadays, opinions different to one's own are always the object of censoring campaigns. If one dares blurt out something someone finds offensive, one is silenced or insulted. Free speech is precisely that - free speech. On the Internet, if one encounters someone who has opinions which violate one's own expectations (for example, perhaps he/she is against same-sex marriage), my personal advice is to block him/her, ignore him/her, and move on with one's life. What he says may not appeal to you, but he has the legal right to say it, and you cannot take that away from the person.

Except when what you say clearly and severely violate the public interest, i.e., promoting terrorism.
