Boomershot is making a good point. Don't trivialize it.
Every year, there are fewer young people in the shooting sports than there was before. Demographics is destiny, guys... we are sliding further into minority status, and further into the abyss.
When I was a kid you could by milsurp rifles and handguns through the mail. The local high school had a rifle team. Those days are never coming back, and in 40 years, we'll be saying the same thing about what we have today.
Our survival depends upon our ability to bring new people into the fold. Many of us go out of our way to help young people come up to speed, or to try to 'turn' liberals into gun-friendly allies. This is a critical effort, and we all understand why. The implications of failure are obvious.
So decide what's more important to you - being pro-gun, or being anti-gay. I'm not asking you to welcome people that you dislike with open arms, but I am asking that you weigh the damage that you'll do by driving them away.
