So, let me get this straight... some people have a serious and honest belief that homosexuals should have equal rights when it comes to things like marriage, those people decide they don't want to support a game because the money may be going to one (or more) people who actively fight against homosexuals having those equal rights, and you think that's a stupid attitude to have?
I don't know your situation, but it's possible that you don't give a damn about this cause because you have no involvement in it. It's easy to brush things aside when they don't affect you. For the people on here, and elsewhere, to whom the rights of homosexuals is a big deal, it makes perfect sense that they might not want their money going to such people.
I really wanted Shadow Complex, but now I may have to re-consider. Yes, fine, I'm sure EVERYTHING can be linked to something bad. But buying a pair of shoes when I need shoes, and not supporting a piece of entertainment that I'll get along just fine without are two totally different things. The people in this thread who are laughing at those taking this seriously, and are pulling out the "well now I'm going to buy the game haha!" are pathetically immature.
If you don't agree with the opinion that maybe this game should be boycotted for this reason, great, I can totally respect that. But to mock others for thinking this is a serious issue is nothing but childish.
