I'm not going to go through the whole discussion, but here's my experiences and beliefs.
1) my sister in law is g.ay, is married in mass, and has a kid. I'm sorta disturbed by the kid thing because i'm a little afraid that that child is going to grow up thinking it's normal to have two mommies. They have friends who are g.ay, and who have kids. the oldest boy (about 2) was running around in a skirt at a recent birthday party for my neice...everyone was calling him pretty.
so, how good of a chance is he going to have to grow up straight? how about my neice?
2) a friend of mine of over 10 years told us recently that he (well, i guess she) is transgender. i still don't know how i'm going to deal with this one... but it really disgustded me, mainly because i didn't understand a lot of stuff. after reading a few emails from him, i understand a little more of his issues, but i still think it's wrong.
people say this doesn't happen in nature. id unfortunately have to disagree--look at clownfish...maybe we're more advanced intellectually, but we're really just animals who can think a little bit more, so our bodies/minds are still maybe under nature's rules. who knows.
i must admit though, that if you're going to use the "two consenting adults should be able to choose" argument, then you CANNOT be against in-cest or polygamy. the problem is g-ay/lesb-ian etc has become less taboo over the years, and it's becoming "normal" to be g/l. in-cest/polygamy is just too taboo to be legal yet.
i hate though that the state legislatures are too afraid to do state/country constitutional amendments. this is just paving the road to let judges make things legal based on their own agendas. don't blame the judges people, blame your legislature...vote people in who will stand up for "family values" who aren't afraid to tick off the minority of the voters who do care about samesex marriages. get the constitutions amended so the judges can't make the decisions.
