haha wow no that is not. but hes only putting himself in danger.. its not like he's doing this shit at a range with unaffiliated people around, its him and a camera, maybe some other people off camera but whatever, they are all knowingly blowing shit up.
skiings not irresponsible because you try dangerous stuff and occasionally break something. driving race cars doesnt promote irresponsible driving because you're driving insanely fast on a purpose built race track.
and as for ear protection, big deal, its his ears, he's not promoting not using ear protection. my grandpa grew up shooting, worked in the miitary with artillery/missle/bomb testing, never wore ear protection and his hearing was fine.
