Strength disparities are a patriarchal construct

So, me at 4'11 and 46kg, I can lift the same as my 5'7 65kg brother. Keep believing that, reality is different.

Isn't ironic? Because there would not be men worthy of protecting the tribe.

Then why do boys naturally incline towards playing with cars and lego, while girls gather around toys like kitchen sets or baby dolls?

I work with toddlers and I see it happening every time, even though I never said what toys they should play with. I will have a minority going through other toys, but the rest have a more clear preference. Girls liking pretty things and being cute, while boys just want to jump, run around and laugh when one of them falls.

Ironic, when you have women willingly leaving western civilization to join ISIS.
