Ridiculous is right. I have never once seen someone so vehemently deny the utility in basic firearms handling technique.
It's better safe than sorry, as they say. When the consequences of poor handling technique can result in death or massive bodily harm, I would assume that saving effort would be last on the list of priorities, but I guess that doesn't apply universally.
You're trying to argue against years of established safety techniques that were developed by people who spent their entire lives around firearms. Safety concerns are safety concerns because it's almost guaranteed that someone at some point has died because they (or others) didn't take those concerns seriously.
If you're more concerned about ease instead of absolute safety, it might be time to take a step back and evaluate on an objective basis how you treat firearms. The consequences of a lapse in safety are too dire to try to take the path of least resistance.
