That's my point. It's not antiquated when you need a no-kidding physical block of the trigger for kids who don't know enough and haven't been trained enough to keep their proverbial booger hook off the bang switch. Hand a firearm to an untrained person, and where does their index finger go? Bam. Right on the trigger. DA/SA or Glock-type actions require an at least semi-trained user.I don't disagree. I was responding to @insanebikerboy's comment that having a thumb safety is antiquated. I've had to get dudes and dudettes like you mentioned weapons-qualified. I even saw a few try out for the VBSS pipeline. I don't know what's more worrisome, the fear that many in the Navy have about guns or the many people who join up and cannot swim (even after being trained).
