Assuming that you're not trolling: 1. Plenty of gay people have stable monogamous relationships/marriages. 2. Marriage isn't only for children. Marriage has legal and tax implications. 3. I like having a stable relationship, I don't like dating and switching partners. I like deeper connections with my partners.
Because the first point is challenged: https://www.thegaytherapycenter.com/gay-men-in-open-relation...
> Several research studies show that about 50% of gay male couples are monogamous and about 50% allow for sex outside of the relationship. The research finds no difference in the level of happiness or stability among these groups.
I think it's a bit rich to use an opinion plucked out of thin air to call someone else's words misleading.
