My issue was with your wording about how you would immediately eject an OCer but welcome a CCer.
BINGO
I believe I took his wording the same way you took it. Like a kick to the gut.
Seriously, if someone politely asks me to cover a gun, or explains they are gun friendly but their policy is that it be CC'd only, then I'm probably going to have no issues complying. But to promptly eject me for simple OC, that seems a bit over the top.
