Why do they do this?

I have heard masculinity decried as toxic. That's very sad...
BTW, there is evidence that marijuana use interferes with testosterone and may be one of the reasons for the development of "man boobs"

I'm not worried. I'll just identify as a male with a fit and developed physical body, so what's the issue?

If I can barely walk-up a flight of stairs, then that's your problem because you aren't honoring my identity and should have made stairs that weren't so blatantly enbyphobic.

The media is getting totally stupid, they need to find something else to report on MAJ Dale E. Wilson, Ph.D. , that is of relevance.
