The problem in marketing feminism to young men is it many of them have not personally experienced, or at least understood, how being a man gives them advantages in society as opposed to women. Young men also have a difficult time understanding how easily they can be viewed as toxic, creepy, or even dangerous without self control and respect for others.
I wish I had an answer, most of the young men in my life are more right leaning and think “feminazi” is a legitimate wat to describe left leaning people.
I think the point is that incentivizing people to have more sex isn’t the answer to a declining birth rate.
