Ah, understood.
I would like to see some sort of experiment between using these cards and slapping someone— although, slapping is pretty rare. What happens most of the time is the woman feels incredibly unsafe and awkward while she tries to understand the reason all those people are just watching her get assaulted.
So really, if you see this behavior, please step in. Tell the asshole he needs to get out. Make it known his behavior isn't appropriate.
