The fact you circled the table twice definitely makes it sound like you were the aggressor. If you have the right to threaten people for being obnoxious most of us won't make it out of puberty.
Who decides when you're being too loud in public? Who gets to judge when using the cell phone is impolite? Anyone with a gun? What you did was wrong.
You enforced the negative image of guns and made it tougher for those of us who want to carry them peacefully.
BTW, I carry almost every day.
"Carry" or "Liscensed to Carry Concealed" if for one purpose. Self defense or the defense of others. "Intimidation" is not part of the deal. This kind of behavior is used against law abiding gun owners in legal forums. (NRA member)
