These activists support the idea that gender is suppose to be fluid or a social construct. It's the only way they support denial like letting trans athletes compete in sports if there where no hard differences.

However, I believe everything is biological or at least has a reason that comes from genes. These ideas fly in the face of "equality/diversity" that Social Activists want to remove.

It's the exact same with race. Radical ideas like Affirmative Action or Reparations only exists when you deny that Race differences come from internally and not the environment. Thus race is something you're born with and not a "construct".
