I don't see where they had to make that compromise to get permitless carry. The votes weren't even close.On the original point, I'm not opposed to public trust parks banning open carry. CC IMO is more "polite" and so long as they're not trying to ban all carry, I think it's worth the compromise to get Constitutional Carry. JMO, YMMV!
IMHO it is just political pandering and the NRA and OK2A apparently support the "compromise".
No matter how you slice it, laws against open carry are infringements on Constitutional carry.
