Are you saying it is not ok, that it is a sin  to simply BE a homosexual? I'm talking about existing, not actions.  Identifying as  gay is about identity, not about a "lifestyle." 

We probably prefer no high school students be sexually active until they are old enough to handle the feelings and situations sexual activity involves. But would you suggest heterosexual students not embrace and accept their heterosexuality?  Should heterosexual students not acknowledge that they are attracted to the opposite sex? Should they hide in shame?
