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’m happy for your realisation, OP!
For me it was homophobic and ableist slurs as general words for “bad”. It’s very common in my native society, so after I started learning more about social justice issues, it took a few years to wean myself off.
Also, looking back, I realise now that in middle school I was lowkey cruel to some classmates, manipulated them for my own amusement. I was never one to bully others, but I was often a bystander entertained by others being bullied. (Even though I was being bullied myself by the same people on other occasions. But I somehow never made that connection with their other victims, I guess my empathy wasn’t fully developed back then. Or maybe it was a mental self-defence mechanism, idk.)
