Wow... that's somewhat condescending, no?
"Disrespectful" ... "ethical" ... And, of course... "assumption". Well, you know what say about making "assumptions"... it makes an ass out of U and mptions.
Kidding aside, there's something kind of... preachy, and fudd-like, in your pronouncements. A LOT of guys hunt with semi's. That does not make them "disrespectful", "unethical", or "bad shots" who need to "learn how to shoot accurately". Some guys with semi's I know could out-shoot you and your bolt-gun any day.
