It's because our founder, Redd, had a bold vision for the future of the internet. And by "bold", we mean "literally everything on this site is a bright, pulsing red that will blind and/or induce seizures in anyone who tries to read it for too long."
But seriously, it's because we're trying to make a statement. A statement about the importance of making a statement. And also because we're secretly run by a group of highly caffeinated, red-obsessed squirrels.
