There's a certain user who has been a troll on this site for a number of years, known as purgeboy. He makes accounts, says racist or violent stuff, gets deleted, and comes right back and does it again. Even with the name blocked out I can tell that that is him.
It says a lot about the conservatives here that those comments got three upvotes, but that guy is just a loser and a troll and nobody really takes him seriously.
