I was a mega tomboy, too. I didn't stop until I was about 32 or 33. My antics included running under a utility truck as it was pulling out of a petrol station. The PG & E guy working on the other side busted up as I raced on. I guess I didn't give the driver a heart attack, but my flatmate says I almost gave 'it' one when I threw myself over the road divider in front of the Pruneyard on Bascom in San Jose. (It was taller than me, and when I worked out I had the strength weight ration of a in shape sausage casing. I used to do parkour lite.)
Destructive traditions. Circumcision, both genders. Any body modifications that disable you. Some they don't do anymore, like foot binding, some they still do, like the rings around the neck like the Padaung chicks or 'giraffe women'. I put stiletto heels in with this. My stepmother got messed up from wearing heals, and she wore more conservative heels, not those crazy 4 to 6 inchers. I also think spending insane amounts of money on lavish rituals is destructive, considering you could have spent that money on more practical matters. (When I was stoopid enough to get married to the thing I used to be married to, we went to the courthouse.) And right now, so is putting your money in the bank, considering it isn't legally yours anymore, and the bank can just use it for bail ins. (What little we have is in a credit union.) Oh, and how about eating and feeding your family toxic processed food on a grand scale where you can't pronounce half the ingredients? I'm inclined to put credit cards in this list, too. Again, I never had one in my 56 odd year life.
I don't think one gender is smarter than the other. They seem inclined to use their intelligence in different ways, if they have any. And I wonder if that's due to programming. I read Japanese chicklets just as good in math as their untwatted counterparts. ( I wasn't really interested in the more abstract math in school, myself. I got C's, never got the hang of proofs in geometry, and never needed to know how to do them in my entire life. No one explained to me how they worked, either; not that I asked. But I did great in the English classes, so here I follow the stereotype.)
Stereotypes. If a former boss didn't rescue me from working at a garage many years ago to go back into lettershop, I'd be a car mechanic now. I'm glad that didn't happen. I'd be making a lot more money, but what state would I be in physically? My back hurts just thinking about the time I dismantled a waterpump.
