Great post!
I too think that "Brave" probably often = "Wow - no option for epidural!"
However, I WILL say that
*I* DO think there's a degree of bravery. (and I'm a pro-HB Mom who will plan an HB whenever we conceive #2.)
Because it's so controversial! 
Because if something IS wrong with the baby, many of your friends & family are likely to think it's "your fault" & you were "reckless" & "endangered your baby" by being at home.
Whereas, if you're in the hospital at least they "did everything they could" (even though we all know that many times the hospital interventions CAUSED the very fetal distress they subsequently intervene to solve.

So, personally, I DO see a degree of braverly in choosing HB in America today. Simply because, so often (and in my case), you do so at the opposition of your friends & family & face their judgement that you're endangering your baby.
