The Bible indicates many sins. Are the members of this group all innocent of all of those sins? How do they monitor this? They can't pick one sin and rank it above all others as a membership requirement.
I agree, as I stated in my post, gay men/women who are intentionally joining these groups to start trouble are 100% in the wrong. But not every gay person interested in these groups has malicious intentions. Those are the ones who deserve protection from discrimination.
