Granted, there are numerous dysfunctional heterosexual couples too. My experience though is that people who partake in the "alternative lifestyle" have far more issues and complexities in their lives. For any of you lib lurkers out there thinking "yeah, their lives are tough because you dogmatic conservatives make their lives hell" no, you're wrong. From what I have seen these people do it to themselves, it is a part of their personalities. There seems to be some correlation between homosexual behavior and, shall we say "less than optimal" life choices.
I can totally confirm what you’ve seen.
The gay males are completely committed to each other only as far as they are both on the lease or mortgage. They openly admit to sleeping around, going on “hook up” via websites, and even doing it for money.
The lesbians are in very manipulative and mentally abusive relationships. Some are borderline psychopaths to each other. And most of them are from divorces with men, and their kids are constantly having to deal with the drama.
