Me personally? I’ve become much less tolerant of sexist humor. Back in the day, cracking a joke at women’s expense was pretty common when I was a teen. As I’ve matured and become aware to the horrific extent of toxicity and bigotry pervading all tiers of our individualistic society, I’ve come to see how exclusionarly and objectifying that sort of ‘humor’ really is, and I regret it deeply.
I don’t think it is univerally okay to make assumptions about someone’s personal identity before you know it. I am happy calling someone sir or ma’am after I know their gender identity. But in a casual interaction between strangers, there is no need for it at all and it is just an ingrained and outdated social convention that I personally am striving to move past.
