You are partially correct. As far as I know, the Scouts do not engage in "witch hunts". Do you really think that the homosexual activists behind the attack on the Scouts really give a darn about the "rights" of what has to be an extremely small percentage of gays who might happen to be involved in scouting. (We're talking something like .00000000000000000001 percent of Scouts who may identify as homosexual.)
No, it's all about ideology with these people. What! You have a rule that says we can't be openly gay. We'll show you! I believe this is their mindset.
I'll tell you, I used to be a live-and-let live type with regard to homosexuals. That is, until our Boy Scout troop came under attack in our town, our public school has started teaching about how to engage in homosexual sex in our high school, and we discovered that the last pastor of our Catholic Church was a homosexual teenage boy rapist. When I'm told that my sons have to go camping with homosexual men (who DO have strong sexual attraction to teenage boys) and put under their authority in close situations, then a BIG LINE has been crossed. I'm ready to fight now.
Or maybe it is much simpler. I think it is not an ideology but plain lust. Homosexual activists (including the ones in ACLU) want desperately to get access to the boys. They want to abuse them sexually.
