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 think given enough time it could make a comeback. A few generations of people who used it to refer to the developmental disability will need to die off. Language changes and insults come and go. I’ll be dead for sure, but in the meantime when something inane is happening to me I can still go back to my childhood vocab and think to myself, “This is retarded.”
