Feminism is about a 5 year old, thought.

[Relax]

Feminism has nothing to do with women playing in the NFL. It's about basic human rights. Women should be paid the same amount if they are doing the same job as a man. Women should have equal representation in politics and business. Women should not fear for their safety walking down a street alone. This is just scratching the surface.

Often times in a relationship women are expected to do all the housekeeping in addition to having a full-time job for which they are paid less than their male counterparts. Women also have to pay more for hygiene products (the so-called pink tax: https://en.m.wikipedia.org/wiki/Pink_tax).

Couple that with the fact that more women are far more likely to be murdered by their spouses (an average of 3 women are murdered by an intimate partner every day in the US) and we start to see the bigger picture:

Our society actively disempowers women. They have less access to resources since they make less money and have to spend more on necessities, they have less time as they often have the burden of maintaining the household, they have less representation in politics and the courts which decide laws that affect them and often they have little agency in their own lives as men can use violence to shut them down if they "step out of line."

This isn't even going into the treatment of trans individuals (which is a touchy subject here given the sometimes shockingly conservative attitudes towards gender).

I agree... AND it's about women playing in their own NFL teams
