Do you think a slight or partial interpretation of sexism (even if misconstrued completely and therefore a false interpretation) will be treated with this nuance and proportionality you speak of by someone who wishes to publicize and cancel as described in this article?
The entire point here is that whether 9/10, or 999/1000 interactions with women go exactly or even better than interactions with men, it ONLY TAKES ONE to literally ruin your life. Get it?
Because of this, the natural defensive reaction is to avoid interactions and conflicts altogether, out of abundance of caution.
Is this sexism? Who the hell cares! Peoples livelihoods are on the line! That you would care more about your little intellectual exercises and nuanced view of the "isms" means absolutely nothing compared to putting bread on the table, or not, for most people.
One could even say this makes you privileged to even think they should care about this more than protecting themselves and supporting their families.
The people that are making these binary determinations to wield social power could not care less about the academic nuanced views everyone is discussing here in the comments. They are not acting in good faith, so reasoning with them will not work.
