Talk to anyone in law enforcement. Lesbians have some of the most violent domestic disputes you can imagine. I don’t know why, but uncontrollable rage is frequently a part of their lifestyle. Again, I get this straight from cop friends and also firefighters who have done arson investigation. Some of the stuff would raise the hair on your back.
Domestic abuse by gay men is also pretty violent. In a heterosexual relationship, the man is generally constrained against hitting his woman by social and legal consequences. A lesbian who feels betrayed by her lover is much less constrained
You are correct. They also have the highest rate of murder/suicide cases when comparing percentages to hetero couple or homo male couples.
