Sure they have. IF he hadn't been openly carrying then nobody would care that he asked a bunch of drunks to keep quiet.
Our objections are about his poor-judgement behavior, and his intimidation with a weapon
Openly carrying a firearm DOES NOT equal intimidation.
Of course, many here believe otherwise, as they believe open carry is "poor-judgement" in and of itself.
I have shown the dictionary definition that demonstrates he was "brandishing." Others have cited the state (Montana) law that shows that that is a felony. No one who has lobbed here has spoken against open carry--you have inferred as much, because we think the poster demonstrated very poor judgement.
