Dude, you speak authoritatively with absolutes on shooting/firearms aspects in which you are 100% incorrect. You've been called out by several forum members over the last couple months (your lack of training while judging "untrained" folks, your vast amount of experience on dealing with the public after being an RSO so little the ink on your card hadn't even dried....for starters), and you just need to stop.
Specific to your shoulder holster comment about being unable to draw without muzzling yourself...you're just plain wrong. End of story.
