Perhaps, but there certainly are some incidents which are ambiguous. I fear that by taking that mindset we will create an environment where people have more incentive to not speak to or interact with women because they might get in trouble for an action that was either careless or consciously intended not to be sexist but gets twisted around and made to look that way. I certainly think that saying something like "you are less capable because you are a woman" is sexist but saying something like "your dress is fun" does not unambiguously imply that it was a sexual advance. Why can't it just be a nice unthreatening comment?
