Am willing to look at another source that is better researched. But yes, they are way over-represented among both serial killers and child molesters.
Also, their crimes tend to be exceptionally vicious and debauched. They don't just stab someone. They stab them 50 times and try to cut off their head. They also like torturing their victims.
Can't remember exactly where I accrued this data, but it was right about 1/3. I used to have more time than I do these days.
Either way, you're dead on right about the absolute savagery involved in their murder tactics. It's not just wanting to kill, it's wanting to torture.
Talk to any LEO you have an honest relationship with, and they'll tell you the worst type of domestic disturbance is a couple of lesbians, followed by a couple of sodomites.
I work with several lesbians, and although they don't divulge the details of their relationships, when asked about their social lives ("what are you doing this weekend") it transitions from "We're going antiquing" to "Nothing really" coinciding with a bruised face or knuckles.
Shame, because they're really nice people, but their romantic relationships are toxic.
