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 miss "Retarded" so much for how it was used in slang but it's pretty irredeemable as a word at this point. Nothing really replaced it as a call-out, which sucks.
Even before it was considered offensive, I generally took the Michael Scott route with the word.
I feel the same about the f-slur for gays. I'm in the LGBT + community and still miss that word too.
