It's neither a mental disease, nor does it require physical engagement. As I said before it's a noun and is the same sex version of the noun and opposite sex word heterosexual. John O doesn't get to define words.
"disease"
I thought the act was a sin?
"If someone never commits the act of homosexual behavior then they are not a 'homosexual'. Only the act gives definition to the disease"
Utterly ridiculous.
Homosexuality was classified as a mental disease prior to DSM IV (might be three. I've had some tragedies in my life recently and I'm still not up to speed again) When it was dropped due to political, NOT MEDICAL, reasons. This is highly documented and you'll find the details in the Homsexual Agenda list of links on Scripters profile page. I believe little jeremiah also posted a link to the list n this thread.
