From Bearing Arms:

However, maybe it is time that we spend a bit more time declaring our allegiance to the Second Amendment publicly. I’m not talking about telling your friends you support it, either. I suspect the average Bearing Arms reader’s friends and family are already aware.

No, I’m talking about wearing pro-Second Amendment clothing, brands, and other such items. Wearing a Glock ball cap while wearing a snarky pro-gun shirt will signal to people that you support the Second Amendment. If people see it enough, they’ll come to understand that we’re all around them and represent no threat. We’ve always been there, and we’ve never been a threat.
