I'm fine with gay marriage but not with them having children.
Personally, I think many kids would get bullied (they shouldn't, but it's the harsh reality) if their parents were of the same sex. These kids should not suffer for a decision they had no part in making. I mean, their friends will have a mum and a dad and surely at some point will wonder what it is like to have a mother or a father.
This is ludicrous. If you have red hair, should you not have children for fear that your child will also be red-haired and teased a "ranga"? If you were Jewish at the height of the pogroms, was it wrong for those parents to have children who were Jewish? Because i can tell you, bullying back then was a lot worse than it was now (hint: maiming and killing).
Someone mentioned a 50/50 chance of being bullied. The actual figure of kids being bullied in school is a whopping 20%. Should nobody have kids because there's a 1 in 5 chance they'll be bullied at school? That is utterly absurd.
Just because bigots and assholes exist and do their retarded best to make life hard doesn't mean you just sit there and let them win. You try the best that you can to make the environment safe. As someone already mentioned, would you rather they be an orphan? Or with parents who never wanted them and/or don't love them?
I don't know if you've read the papers lately, but the foster care programs in Australia are riddled with child abuse. There are many people who do it simply to get the pay cheque and then neglect the children to try and 'profit' from the government. There are also some sick, sick people who do it so they can get a slave and either abuse them physically/emotionally and sometimes, horrendous as it is, sexually abuse them as well.
But no, I'm sure an orphan going to a homosexual family who has battled through some of the worst adversity imaginable to try and adopt a child because they want to give it their love IS FAR WORSE than neglect/no parents/sex abuse. In the end, by not having read into the issue in the slightest (as evidenced by your malformed opinion) you actually number as one of the ignorants (but I wish to clarify that I do not think that you are in any way a bigot, as your intentions are good, but are simply misguided) you so decry in your post who stigmatise homosexuals and prevent them from attaining the level of respect and decency that they so completely deserve.
What's actually happening is that denying homosexuals the right to adopt is depriving innocent children of an exit to the cycle of abuse in the foster care system. THAT'S what's actually hurting kids. Not some perceived threat of being bullied, but actually being abused in the system as it is, because there is a dearth of decent people either wanting to or allowed to adopt.
Finally, read any study about children from homosexual parents... the results mainly vary from children of homosexual couples having the exact same to a slightly higher quality of social/mental/educational development than those children of heterosexual couples.
