Why are people so afraid to be associated with what they write online?
If you wouldn't stand by it IRL why post it online? Is it really that important to your life that you are able to be a troll online?
People will say things like "I could get fired", well if that's the case you either have a shitty job or you are a shitty person who deserves it. But most of the people who are against this don't have jobs anyway. So what are you afraid of?
It's also funny when they think that impedes freedom of speech. Freedom of speech does not mean freedom from the social ramifications of being a dumbass. You can say whatever shit you want, but be prepared to defend your stupidity if it's that important to you. Don't go crying "censorship" just because people suggest you stop being an idiot.
