In the 70s and 80s the powers that be in the education system determined that the language used in school was boy-centric.
This is never more prevalent than in our higher education system now. Visit any engineering college in the United States. From Maine to California, you'll find that the overwhelming majority of engineering courses are occupied by non-American men. American women, not so much, but non-American men: everywhere.
The feminists literally bred the curiosity out of our boys. Schools used to feature hands-on hard sciences. We used to play war and tag and capture the flag in the school yard during recess/P.E. Now the boys are disinterested in anything that doesn't involve TV, video games, or sex.
Political correctness has destroyed everything about the essential human experience we all KNOW to be true. Political correctness is neither political nor correct. It is destructive and wrong, and we really need to do something about all of this crap infecting our society.
Thanks for your comments. I agree...
