Um... No crap.
Our deafness is invisible. Not to mention the Deaf culture itself is probably around 1% of the American population if I can borrow Gallaudet's estimate on how many ASL users there are. I wouldn't be surprised if TTY (or other form of text-based relays) is on par with VRS considering how many people out there don't know sign language, but are deaf or hard-of-hearing.
No matter how we go about it, it's a constant uphill battle.
