re: Why is Reddit such a leftist cesspool?

I was on Reddit last night - I have to use it for work (IT related) frequently in order to get a quick answer or research things. No politics in those subreddits, but inevitably I go check out other interests. I was on a forum and someone asked "why do people smoke in this day in age", and it seemed like half the people in the thread were former heroin addicts who said smoking was harder to quit. What a bunch of losers.
