You mean like the collapse of the family after "no fault divorce"?
Oh, people like you won't recognize it because you still think it's normal to have children raised by single moms who don't actually know which men fathered the babies.
Same-sex isn't actually going to cause anything as much as it is the result of something. And because they want to be accommodated, laws will have to change which will inadvertently give others the short end of the stick - mainly children.
But I don't expect people like you to uphold anything when you aren't a part of anything. When you've decided to grow up and contribute to society, maybe your rants will have validity. As of now, you don't even have the backbone to let us know your real status, your job, your religious affiliation, etc. You're too much of a coward that anything you've written will be used against you.
