OP is saying we should be taught not to hit anyone at all instead of just saying not to hit women. This is true and the fact that this got lost in “translation” for a lot of posters shows the intelligence level of this site.
Most of y’all should know that women use that line of thinking as an excuse to get physical with men anyway.
Problem is, this goes without saying. At no point in my life was I ever taught not to hit a women, if a girl hits a boy in a classroom setting, they will be written up in most cases, and vice-versa. When we are talking about adult women hitting men, this isn't something that we can root to whether or not it was taught in adolescence and as a result trace it to a reduction in chance that said women will hit a man. Simply put, no well adjusted individual is going to strike another individual. The consequence for striking another individual could punishable by law and possibly punished on the spot by the individual you decided to strike. Recounting the times I have been struck by a women, they were all by mentally unstable people that I would never deal at this point in my life, the most prominent of that group was a girl that liked to slip up on her bipolar medication. In a numbers game among humans where emotions are running high and there are clear power dynamics at play, a % of the population of women will almost be guaranteed to hit a man and vice versa.
Think about it, did being taught a child not to steal (I was personally never taught this or at least I can't remember) deter you from stealing in adulthood? Likely not, what is more likely to steer you away from stealing is the consequences for stealing. We could get into the moral/ethical dilemmas of stealing but this isn't something that can be grasped until later in adolescence and adulthood (18-25), in line with our understanding of the development of the prefrontal-cortex. So if we are looking to deter the remaining % of women that are likely to strike men, it needs to be top down, men need to be more likely to report incidents of physical abuse and given the laxing of societal pressure to do so without being seen as weak and women before a judge in cases involving domestic abuse need to be treated equally under the law. The latter part we are seeing evolve with time as society approaches the criminal actions of women from a more neutral stance, you can observe more women being handed life sentences at this point, there is obviously more work to be done on this though.
