I'm not sure if you got to see their comments before they were deleted, but I recall their comment being a bit weirder than that. Things like "sometimes my family forgets to pick their wet towels off the floor. What happens if you add a gun to that?".

As the second part of your comment, yeah I see your point. That being said, the rules of gun safety aren't as huge of a hurdle as people seem to think they are. I think it's more that some people are repelled by any form of friction when starting a new activity.
