I know what a boy is -it has to do with the plumbing. However, 'gay' has to do with how the plumbing is used. You seem to attempt to combine a state of being with an activity WHICH is what the left does. The left does this for one reason and one reason only... Why do you do it?
Taking that as a friendly question: I use the word "gay" as a description of a perverted attraction or a disordered mental state, not as how the plumbing is used (it shouldn't be used at all at that age). I would hope that few straight boys in BSA are sexually active and that leadership and parents would strongly discourage that activity and offer interesting alternate activities that are much more likely to come to fruition than dreams of early sex. I would hope that no gay boys at all in BSA are sexually active and that leadership and parents would discourage that activity - more strongly for gay sex than for straight sex, but very strongly on both accounts.
