Believe me I see way beyond the politics of this game. My kids love it and It really doesn't matter to them if the aliens are good guys or bad guys... People read way too much into things... If an Alien shoots at me I am not going to try and reason with it.... see I am not a liberal and neither is the alien.
How else can one maintain a permanent bad mood? Some people need to have someone to boycott, be pissed at, or feel as though they are out to get them.
