Yeah, you've done this before. I'm not quite sure why though, you should know my response by now. I barely know Skaar so I don't have the faintest clue. I only swoop in with anything resembling a strong opinion when I'm versed in both characters/teams. If you removed the posts of people who posit an opinion based on intricate knowledge of only one side of vs. battles, you'd have a vastly less-frequented forum.
The only exception I make is to correct blatant misinformation about a character. But even that, while sometimes seeming like an endorsement of a character in a fight (mostly to the over-contentious members of the forum), still isn't an opinion on the fight itself. Because, really, I'm self-aware enough to realize that while I can bust in to school people on a select number of characters, I'm equally as likely to be ignorant of others that I don't often read. Most forum bias is just because of what we've been exposed to in comics, not because we're incapable of arguing against a character we like.
