This could probably work if we could wave a magic wand and change everybody’s attitudes overnight. But as some of the other commenters have pointed out, a single woman can’t do this in a society that is wired up to assume any friendly woman is “asking for it“. Society could evolve this way if all men got scared enough of the repercussions of talking to strange women. Then women might start talking to men as that would be the only way romantic encounters could ever happen. But it looks to me that online connection has provided a workaround for dealing with this climate of fear. meeting friendly strangers face to face is probably going to become a thing of the past, if it hasn’t already.
