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.
Man what the fuck, “rule of thumb” sounded like the most innocuous and random shit, why must you do this to me.
Take a look at the Wikipedia page. It really is innocuous, it actually originated as a form of measurement like feet.
