ELI5: What are the non-religious reasons for opposing gay marriage?
gpt
* the gov't has in interest in supporting traditional, children producing marriage
* homosexuality is a psychological disorder, not a lifestyle, and the gov't should not support it
* gay unions are fine, but that's not what the word marriage means, so that word should be reserved opposite sex couples

I don't want to suggest these are particularly *good* reasons, but they are reasons people use.
