It's not nasty and I wouldn't mind if i had 2 dads, 2 moms, etc. If they can raise and care for a child then I don't care. I can't tell if you're an adult whose been raised to be intolerable, or a child who's been pressured into it. If you're the former it's probably too late for you. If you're the latter you should understand that it's perfectly acceptable. You should speak to your guidance counselor at school if this is the case.
I always avoid talking about controversial topics on video games, because I end up discovering some of my close friends are thick minded-racist/homophobic old fashion pricks that have no idea the world is changing and is no longer lead by the bible.
