I don't wear a wedding rings per se but sometimes I wear rings on my left ring finger. It's an accessory and that's happens to be the most comfortable finger to wear it on

Yes. Women who work in bars/clubs/casinos etc sometimes wear them to keep men away.

I wear a ring on that finger, but it isn't a wedding ring. You need not to be wed to wear a ring or to wear a ring with a name on it. Also there are less obvious chains to wear.

Yeah, most likely as a deterrent against creeps. I think nothing of it. it’s their choice if they want to get hit on or not.

Maybe they don't like to live like a property.

No I haven't. Actually, I'd have no idea if I have. (a) I don't notice wedding rings, and (b) I probably wouldn't know whether they're married. I think it's fine, whatever floats their boat. I'm glad they have the gumption to think/act outside the box of tradition/conformity. On the other hand, it is a little deceiving.

Yes. It’s fine. Some women do it to keep creepy people away. Whatever… it’s fine w me.

I assume everyone I see with such a ring is married

Yes, I have some lady friends who were waitresses and bartenders and whatnot and that was a tactic to get dudes to back off, whatever works
