Its the old "slippery slope" argument. Where do you draw the line? Other people have claims that strike people today as bizarre but no less justiciable. You can't limit marriage rights to gays and lesbians only. That's to use their own argument - writing discrimination into the law. Restricting marriage to a man and a woman avoids this problem and its a positive form of discrimination because it benefits the entire society.
"Show me just what Mohammed brought that was new, and there you will find things only evil and inhuman, such as his command to spread by the sword the faith he preached." - Manuel II Palelologus
Restricting marriage to a man and a woman avoids this problem and its a positive form of discrimination because it benefits the entire society.It also has a pretty iron-clad foundation in the laws of nature, as well.
All homos have is "two people love each other."
What in the world does that matter?
