Have at it, I'm driving 3 hours to watch the race, not carry my rifle around outside the stands.
I get it Nascar is evil because they aren't going to air ads with AR-15's in them anymore. I honestly don't recall seeing any of these ads anyway, and no other sport does that I know of. I see it as more of them getting out of the gun debate then being anti gun.
Really, it's not even that. The ads were for their programs at the races. Just heard that clarified on the news recently. I was thinking the same as you, that I didn't remember ever seeing a commercial for a gun company during any races.
