That's what I would say.
Some here said the guy was a Dem plant posing for a false-flag op. I believe there was some actual evidence - though somewhat inconclusive - to support the claim.
However, even if that's true, I would STILL be glad to see him there with his AR regardless of his politics.
First of all, if he was trying to make us look bad, he did a lousy job of it. He actually makes us look good.
Second I'm all for liberals, blacks, gays, greens whoever indulging in their RKBA. They have rights too, and gun ownership often creates converts for our side.
We have rights; they're us.
