Methinks most of this is blatant recruiting. Reminds me of the Shakers in New England who didn't have sex, so no children were produced. So they went to the orphanages and adopted their children - who bailed out as soon as they were able.
The saddest part is that today all the so called "professionals" are calling this aberrant behavior "normal."
You are exactly right. He who defines the terms will win the argument, and once the sodomites succeeded in having their sickness removed as an official "disorder", their agenda kicked into high gear.
What once was shunned is now accepted with open arms. What once was shamed is now embraced by after-school specials and primetime programming.
