Jefferson was going easy on them. Castration was suggested as an alternative to sentencing them to death.
Either way - I agree. Clearly homosexual behavior (and any other form of abnormal, non-procreative sex) breeds disease. Removing the urge to perform such unnatural activities is an act of compassion. Love thy enemy. Castration would help protect the individual and society as a whole.
It is unfortunate that there isn’t such an easy solution to help the female sodomites.
I watched a documentary (Though, I can’t recall the title) on a man who was a homosexual pedophile and decided to get castrated. He claimed to be much happier with his life after the castration.
