> Walmart absolutely is a supermarket
As I said, even though I'm reluctantly willing to entertain this, it's an incredibly niche talking point. Except for this one corner case which is only kinda-sorta true, people cannot buy guns at grocery stores. That's nonsense, and your talking point is nonsense.
I never said grocery stores and you already agreed that what I did say is correct: You can buy guns at the supermarket in America.
