I watched it and it was definitely not transphobic.
Dave's trans female friend that committed suicide, her family supports Dave and says they believe it's not transphobic.
Every single criticism I've seen has been general. None of them, except the ones which take stuff out of context, have specific gripes. That's how you know this is about shutting down debate they don't want to hear.
There must be some analog to "mansplaining" that fits, here. "Transplaining"? Hmm...
My main point stands: criticism of his special is too vague. It's almost as if many of the critics never watched the whole thing, having formed an opinion about it early on and stopped watching. I watched the entire thing and it is a single piece. There are no standalone jokes in that special. Every single word is in support of the last words he speaks.
I even watched the special a second time to be sure I hadn't been bamboozled by Dave's wit and charm. I felt even more sure after the 2nd viewing that it's not transphobic.
To reiterate:
>> "You'll understand if I weigh the accounts of trans people who watched it over what you, Dave Chapelle, and the family of a trans person who can't speak for herself said."
