You've been repeating this, but do you think this is an actual solution? Some heavily armed young male Arab comes into the club, and the bouncer says, "Sorry, you aren't welcome here!" and then the heavily armed young male Arab is going to say, "Ok" and turn around? I have a feeling you know very well this idea is ludicrous but enjoy thinking that gay bars will be hypocritical in some way when danger comes their way. Either that or you really believe this idea will work to prevent future massacres.
