That is the standards feminist shiboleth, but it doesn't appear to apply in this case.
From the article....
"A Republican candidate for
Mississippi governor has been accused of sexism
after he banned a female political reporter from going on a campaign trip
without a male chaperone for fear of being accused of an extramarital affair."
If this is to be believed, it isn't about fears of what he himself might do.
From the article again, we find the (imagined, IMO) enemy....
"His campaign told her they feared if somebody took pictures of
him with Campbell, they could be used by rivals to smear him."
