Funny (and predictable) how this took somewhat of a left turn on the issue of safety and behavior.
Safety is as safety does. And safe behavior isn't about absolutes (because safety is relative, not absolute), it's about reasonable precautions proportionate to the relative risks/consequences involved.
We can all agree that the consequences of having a negligent or accidental discharge are potentially very grave indeed. (Note the two are not the same, but the potential consequences are.)
Safety is thus layered, especially with firearms. How much layering is desired/required is something based on reasonable assumptions, experience, and personal choice/opinion.
For personal choice/opinion, I don't care so long as it's sound and reasonably safe. Maybe I won't do things there same way, but if it works, why make a "big deal" over it?
We all know (or should know) that the most dangerous time around a firearm is when it's actually being handled. Loading/unloading, holstering/unholstering, etc.
And every firearm is designed differently, requiring different handling actions for various events.
Take reasonable safety precautions accordingly.
If you differ in safety precautions, then discuss them on their relative merits and leave the emotional aspect aside. Technical discussions and the like are much better.
