If you judge 225 year old behavior by today's standards, yes they would be judged sexist. Of course, they would be considered normal by the current standards of the middle East and some Asian countries.
Not even someone as blissfully ignorant as you can fail to realize that morality and standards are, at best, situational concepts related to a society's present day mores. Democrats, for instance, formed the KKK and voted virtually en bloc against the 1964 civil rights act. Unions demanded a rise in minimum pay because it would keep "them damned darkies out." The gratuitous use of drugs was universally condemned until liberals realize how "cool" it was to go to work and drive a car while stoned. Were Democrats and unions bigots?
