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 respect your intuition to drop problematic phrases but you may have been lead astray on “rule of thumb” by a very common rumour (Wikipedia calls it ‘modern folk etymology’) that that is where it originated.
In fact no law ever existed and it was more used in trades as thumbs were an easy mode of measurement available to anyone (similar to the use of feet to measure!)

The Wikipedia article even explains the “switch” rumour and provides some backstory and explanation to it.
So don’t feel weird using Rule of Thumb; it has more to do with carpentry than anything else.
never heard of that, really neat
