It's what I'm going to start calling egotistical masturbation. They want to feel better about themselves so they insult the crap out of you. I know some RPG fans who just love claiming that their smarter than everyone because they prefer the original mass effect to the second one and who absolutely love the witcher because it's complicated and makes them feel smart. Then they call me stupid because I prefer games like saints row 2. But they're the ones that need to insult people to feel good about themselves, and in the end I think it's actually a much sadder life then those of the people they insult. Words only have power if you get offended at them. Remember that.
