Naturally I can't speak for Sally (contrary to my previous supposition). In terms of myself, I might be willing to surrender just about all ground outside that from an ethical perspective (save situations where "flirting" rose to the level of harassment).

As for mapping onto MeToo, I don't think my ethical objections to certain types of flirting have anything to do with MeToo. What I think is or is not ethical regarding flirting behavior is irrelevant to that behavior's presence or absence in MeToo.
