I'm guilty. I admit it. I used to be one of those guys who started crap on the Internet. I'm mostly a Marvel fan, and I used to engage in "flame wars" just to piss off DC fans.
Then I grew up and realized that both companies are awesome in unique ways, and neither of them should be free from a critical eye. Wasting time on flame wars is stupid. Don't do it.
What are your guys' thoughts? Should brand loyalty be a point of division for comic fans, or should we learn to just get along and have reasonable discussions about our differing tastes?
