For me it’s driving while under the influence. If you couldn’t tell, I like me some ganja. However I have long since held the belief that it is utterly insane to drive while under the influence of most substances, with maybe nicotine and caffeine being the exception. All too often I see other stoners smoking and driving, which I simply can’t fathom. I’ve only operated a vehicle once under the influence and it was just to move a U-Haul around the block to a different parking spot, which was such a scary experience while high that I refuse to even consider getting behind the wheel again while high.
A lot of the tacticool is just dumb and awkward; that’s sort of just good fun LARPing nonsense. Some poor choices like not wearing mouth protection are flatly stupid, but at least it only punishes the person making the choice. My problem with lasers is that the person making the dumb choice isn’t affected, only people otherwise doing everything right.
I’ve actually asked a few fields about implementing no laser policies, but unfortunately owners seem apathetic about having to enforce it.
