How come Bigots Are Always Proclaiming That Heteroual Families Are Superior?

Religious bigots will always tell you that a family with only one mom and one dad is the only way to go. I was raised with two parents of opposite genders, and I tell you it was nowhere near perfect. My parents would always fight and I was also phsically abused. I'd rather have been raised by two loving parents of the same gender or two loving parents in general. Seriously, kids just want love, they don't care about gender or ual orientation. But bigoted people always try and p laws to ban gays from adopting or becoming foster parents. I've seen gay parents, and they are completely loving and caring to their children, and the kids seem happier, although I'm not saying it's always this way. But I don't get why there can't be more than one family structure.
