jg, the links you posted largely use apples to oranges comparisons.
The first pretty clearly states at the top that data on homosexual parenting is largely incomplete and spotty. The reality is that there just isn’t enough long term evidence to know for sure if there are any effects, especially once you control for other variables.
Promiscuity has nothing to do with one’s ability to parent.
Comparing legally married heterosexuals and all homosexual couples is ridiculous. I’m 28, heterosexual, never married, and my average relationship has been less than 2 years. A far fairer comparison would be of all heterosexual relationships and homosexual relationships, but that wouldn’t futher the agenda.
The rates of abuse in lesbian relationships cited is comparable to those in heterosexual couples.
Mental health issues for homosexuals is a huge issue in this country. It’s pretty clear that the depression, substance abuse and suicide are largely caused by being part of an oppressed minority.
