What has that got to do with anything? what is the relationship between gay rights and divorce rates?

What I just can't get my head around is how regular healthy marriage is in any way what so ever affected by gay rights. The ONLY people who will have any interest what so ever in a same sex marriage are gay people! They cannot be a part of a healthy heterosexual marriage because it is a lie!

I can't see any mechanism by which gay marriage leads to an increase in marital breakdown within heterosexual marriages.
