In my eyes, if they can't bring themselves to teach children about tolerance and respect, then yes I do believe they are failing their kids and society in general.

I will teach Jazz that everyone is entitled to an opinon, and even when we don't agree we can still treat them with the same respect we want to be given by them.
They're entitled to believe that it's 'wrong' just as much as I'm entitled to believe that its 'right'. (well, as long as their decision is 'informed' and not based on some dumb belief like gay men are peadophiles, or that homosexuals want to take over the world)

Besides, my issue is with kids understanding and being tolerate to Jazz, who has two mums through no fault of her own. I'm not saying that everyone needs to accept gay/lesbian lifestyle. Just treat my daughter with the respect she deserves.
