I follow what you're saying. Here, the gun range itself is the difference. If for some reason there existed a "pill-swallowing range" I imagine women would see the same treatment that lone men at a gun range might experience. Gun and pill ranges both would want to avoid being lightning rods for suicides. They likely need insurance, they would face legal or economic consequences if they're a demonstrated hotbed for suicides, and they don't want their employees and customers exposed to people offing themselves. But we don't get to witness policies against women at pill ranges because pill ranges aren't a thing.

Now, if they applied the double standard to purchasing guns and ammo, that would see the same outcry as men vs women buying OTC sleeping pills.

Absolute gender equality and practical application of double standards trying to reconcile themselves within society is fascinating. At least to me. It has now made me want to see a Rick and Morty universe that has pill ranges.
