If what Jenner did doesn't meet the basic definition of courage then you are ignorant of what the definition of courage is and proving the point of what transgender people struggle with.
Dude, just ignore it. I was gonna dive in & point out how it is courageous, but they'll just dismiss it. They can't understand, mostly because they've never really had anyone close to them who is transgender. They'd be singing a different tune if that was the case. That's what it stems from. None have bothered watching the video, and none have bothered ever considering the plights of someone who is transgender (especially in person).
I'd normally agree with you but in Jenner's case I believe it was motivated by money and fame. It is how that family is run. So was it courageous? Sure but it's tainted in my eyes in this one case by greed.
