1) Male, from the US.
2) Agree. Although I'm probably leaning more towards indifferent because this really doesn't affect me or anyone I know for the time being. It might sound shallow but I wouldn't go out of my way to fight for gay rights. If gays get the right to legal marriage, then yeehaw. If they don't, I think I'll find a way to manage.
3) Neutral. As long as the current societal stigmas towards homosexual couples are in place, then kids would have a harder, not impossible but still hard, time fitting in with other people. Of course I guess you could argue that it's still loads better than being an orphan so I could lean either way. Hence the neutrality.
