> chemicals and a sedentary lifestyle
As for the theory about chemicals I think that can be a good explanation for parts of the problem.
One observation that strengthens this theory is that dogs are affected as well.
> a war against boys that doesn't exist
The war part is a way of speech, or hyperbole, I give you that.
But how about you explain:
- the majority of prison populations being men. Is society failing them like we say about every other group who is overrepresented in prisons or are men more evil? If men are more evil - explain why they are different from other groups overrepresented in prisons.
- why do boys on average score significantly better when tests are anonymous compared to when the tests are named and graded by their teacher?[0][1]
- Related to the first: Why are judges more lenient towards women? [2]
- etc

[1]: I'm well aware that the opposite happens as well. A good friend of me told me how he (who always got good grades) and a female student who always got average grades swapped their hand ins and found that the teacher had still graded his top notch and hers as average, so yes, this happens as well but seems to be less common at least around here.
