Okay, let's break it down one item at a time shall we?
Huh? Where did I say they don't have the right to ask you to be disarmed in their store?
You didn't, and neither did I. This is called a Red Herring. Your exact words were, and I quote from above, "Thanks for knowingly supporting those who have no respect for us." I took this to mean that you were upset with Costco for not "respecting" your "right" to carry in their store even though it's a private store and they can set whatever rules they want.
You should watch your tone when you are wrong.
Am I wrong in saying that you're upset? Because if I am you sure have a funny way of showing it.
Who's the hypocrite, though? The guy who says: "If that's your policy, I won't shop here," or the guy who says: "Since that's your policy I will lie to you that I am unarmed but will carry secretly and still give you my money." Are you sure you understand the word?
Who's being hypocritical? Show me a single Costco with a sign on the door, and I'll show you a fellow who leaves his carry weapon behind. I know their policy. I also know that unless it's explicitly STATED at the entrance that no weapons are allowed then I will in good conscious continue to carry my concealed weapon when I shop there.
It's one thing to feel forced to cover up and shop anyway. It's quite another to brag on the Internet how you don't care because it's just easier to do it anyway.
As opposed to high & mighty bragging about standing by your precious principles while at the same time whining about businesses you won't patronize anymore? Puh-leeze.
