Kids get bullied at school regardless of who their parents are, so this isnt a convincing argument.
Yes, but they might well get bullied more if their parents aren't like everyone else's parents. I don't think it is that unlikely that a child with gay parents would suffer more bullying than your average man/woman parented child.
edit: Also, couldn't you imagine feeling 'different' or left out if your parents were 'different'? That may have a negative effect on a childs emotional state at school.
So you've never heard of single parents? Cool story bro!
Maybe we should take kids away from single parents too because those kids are only being raised by a single gender.
Of course I have, and of course, I don't think an average single parent could do as good a job as an average couple - as a random comparison, single parent families are more likely to live in poverty, and that means a higher likelihood of suffering crime, having lower school grades etc.
Whether this holds validity specifically for single parent families from whatever socioeconomic background of parent compared to similar background for a couple or anything like that, I don't know. I can't find any definitive statistics, but I don't think there are any showing that single parents are better than two parents for a child either, so I'll just stick with what I've already said.
I wasn't suggesting that we take children away from parents who already have them - we already have enough parentless children waiting to be rehomed. Anyway, that would just end up being a stupidly cruel, ineffective, and disruptive system if we tried to take children away from families that by some measure were worse than others. What I was talking about was whether your average straight couple would result in better parents than your average gay couple - who knows! I doubt there are statistics easily available on the subject, I was just thinking of disadvantages that might arise from having single sex parents compare to normal parents.
