Exactly what about the Snapchat or Jared Kushner stories I cited do you believe is a hoax?

Please stop claiming things that were never said. You do this constantly in your comments and it's not fair or productive.

My point is only that the media is not the objective truth or overruling expert in any single subject, and often filled with highly-opinionated, ideological, and sometimes misleading takes.

As far as this specific issue, I disagree that it is so widespread across the industry outside of a few companies with clear problems. Also the Kushner story seems to be mocking their appearance than behaviors.

The exact same behavior is present in people that have zero background in frats. How do you explain that?

This is not a "frat bros" problem, it's a misogyny problem. Painting it with the words frat just helps paint whatever biased narrative is being spun to make the story more compelling.
