Are you saying homosexuality is the norm?
It's as normal/natural as heterosexuality in the world, it just occurs less.
If by "norm" you mean "most often occurance" (or mode) then yes, heterosexuality is "the norm", just as silver cars are "the norm". Doesn't make it any less right though or does it mean it's correct to be any less tolerant of it just because it's not as commonly occurring.
I sit on the fence on same sex adoption - on the one hand its not natural, families work best as a mum and dad imo, although there are also plenty of bad cases of that!! Also, I remember how kids are at school, the slightest thing to be used against someone will (be it glasses, ginger hair, rich/poor, fat etc...) and the child will be teased at the very least about this. However, I would love to see all kids in care be taken out and place dwith foster parents, even if they are gay, single parents, old, young etc... as long as they can demonstrate that they can provide a good safe home.
Indeed, having same sex parents/guardians can lead to bullying, but so can hair colour, eye colour, skin tone, freckles, being tall, being short, being thin, being fat, being black, white, or any kind of foreign, having a high pitched voice, having a deep voice, long hair, short hair, big feet, small feet, being an early bloomer, being a late bloomer, wearing glasses... not wearing glasses, the way you dress, the way you walk, your preferences and interests, your social group, your class status, the foods you like, the things you own/don't own...
...need i continue lol? Kids will bully over
anything so the argument that kids brought up by same sex arguments will get bullied, although probably true, is a moot point...
