I've eaten @ GC in a city just west of Milwaukee many times with absolutely no problem.
I'd think that with their support of veterans (free dinner on veterans' day), they'd be in favor of civil rights & supporting the Constitution.
Is that one store owned / managed by an anti, or are all stores corporate & are declaring themselves anti-rights, anti-Constitution, anti-family?
(Anti-family? Yes. As one of Oleg Volks' pictures says, protection of children is a basic parental reaponsibility.)
If the GC corporate guy doesn't think his family is worth protecting, that's his problem. But he can't impose his lack of thought on customers, at least not without a problem.
