I think someone has told you those things are true. I do not think they are actually/necessarily true. There is a great deal of collective make-believe happening within certain parts of the academic/writing/blogging community, tied more strongly to what they'd like to believe is true, than to what is actually true or scientifically sourced.

There's a lot of stuff which can give one delicious Rightousness tingles in our neck when we read about it in books in our 20's, but then when you go out live in the real world as an adult, among normal majority populations and communities full of people with no agenda, you'll find will completely fall apart as utter horseshit. Boys and girls are different. Men and women are different. Have the best 10 white basketball players in the world face off on the court against the best 10 black players and I know which sise side you should bet to win. Individuals can be snowflakes. Groups are not, they show strong trends, esp when genetics/hormones/brain-structural-differences are driving it. Pink girl stuff is not some evil patriarchical oppression -- its because they've done objective tests on large numbers of people over long periods and saw a significant preference to pink among girls and vice versa -- though of course an individual can vary. Have a household of teen girls and another of teen boys and any common sense un-PC american will tell you which one will be burning thru more cellphone minutes each month. etc. "Shoe sale this weekend!" and non-PC/non-University-indoctrinated adults will tell which gender that will get much much more excited about that announcement. Football game today! Again, it's obvious to non-indoctrinated Americans which gender is going to have way more people excited about this fact. Speaking at the level of groups. Without any assumption of "evil oppression/manipulation" having occured. Occam's Razor is a friend when understanding the world.
