I'll say it if you prefer. "Homosexuality isn't statistically normal"
Statistically speaking...being American isn't 'normal' either, Winky. After all, you're only make up roughly 5% of the population of the Earth...that's a pretty wide deviation from the norm. Chances are that it's more normal to be homosexual than to be American.
(Let's not get into a link war over this - let's say that between 3-7% of people are homosexual.)
I personally equate homosexuality WITH pedophilia
Both are deviations as per that statement, right? As deviations, they must therefore be wrong so why compile one deviation with another potential deviation...
so don't let homosexual couples (obvious deviants) adopt and thus expose the kids with another potential deviation (pedophilia)..even though there's no link between homosexuality and pedophilia other than the fact that you consider both 'wrong'?
..and you're using the biological argument now? Biology decrees that they can't have kids so they shouldn't be allowed to adopt either. Pray tell, how many couples who aren't infertile adopt?
If you begin to accept deviant behavior
then you can not object to deviant behaviors.
There's the slippery slope you Cons love so much. That all encompassing line between right and wrong is being pushed in the wrong direction and then you have TEOTWAWKI!!
