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.
Eh, it costs me nothing and actually helps me with a personal goal I have to not make assumptions about someone's identity based on what I perceive. As someone who has been misgendered many times in the past, it truly hurts, and while that may be a personal problem, I don't really love going around potentially causing others to feel hurt in any way.
