Has to do with men not wanting to protect fat women and physically being unable to help them in some situations because of their size.
Being with a fat woman can get you killed.
You're with your hyopthetical big family. Your wife huge. Suddenly it's time to run. You gotta hang back because your wife can't keep it or straight up falls trying to keep up. You hang back and help her along. You or your children are now being subjected to violence.
They're a liability. It's hard to protect someone like that.
You're missing the point.
1. Fat or slim, a woman can slow you down. Slim women can be slow runners as well.
2. They are not only talking about physical protection with "Protect Black women"
But that's besides the point. The real point is those two things don't match when trying to make a point (Criticizing "Protect Black Women" and Criticizing weight). Those are two Red Pill talking points that she is just mashing together because she has heard them before. She sounds like she just watched Kevin Samuels and is just regurgitating some of his points but has no clue how or if they relate. That is basically the female "Pick Me" YouTube space.
