In the vast majority of such cases, something - someone or a series of events - has influenced the gender-bender behavior, particular the dress-up role playing element more than just not liking usual boys activities as much as most boys. The dress-up and role playing stuff is more serious of an issue. When the concern does not have the dress up and role playing elements to it, such boys for the most part are no different than most “tomboys” have always been - girls that liked a lot of “boys” activities but were not and did not become Lesbians.
Scolding against the “wrong” activity for most boys does not work as well as encouraging the “right” activity, Boys are natural rebels, but with encouragement from heir dads are eager to please.
Is the only thing taught in school these days either Critical Race Theory or Gender Identity? Do they even make time for reading, spelling, American and World-wide (true) History, English, science, or math? For those are the frameworks for learning almost everything else. Then add in a few electives in middle school. Those six items I listed above should be the main things taught in schools until you reach about seventh or eighth grade. At that point, more advanced students should move on to higher classes according to their skills.
I’m beginning to think “un-schooling” is a better choice than public schools. If properly channeled and supervised by caring parents, simple everyday life with no structured learning curriculum would be a better education than what children are now receiving.
