The "graphic signs" part is interesting, that's part of the "blunt" thing I think. I'm reminded of a video that was making the rounds a bit ago that was a Mormon instructional tape, in ASL and geared towards deaf people, about the evils of masturbation. The signing and facial expressions were much mocked. I watched it expecting to dislike it and the guy presenting it but honestly, he did a great job. Very skilled in ASL. It was an interesting cultural shift -- I started out watching it from a hearing perspective and seeing why it was so mocked, but then after a few minutes shifted to deaf/ ASL perspective, and it seemed perfectly normal. I had to consciously shift out of that mode to remember why anyone would possibly have a problem with it.
Deaf people think that hearing people are needlessly uptight about this sort of thing. Deaf people are NOT big on euphemisms.
However, that's just the signs, not actually crossing boundaries.
Your comment about the deaf women brings to mind that I seem to know of a lot of organizations devoted to offering help to deaf domestic violence victims. So could be that it's proportionately higher in the deaf community, dunno.
Just did a little Googling, this isn't conclusive but has some interesting info:
Within the deaf community, there is a “double code of silence” related to domestic violence because services are typically not culturally sensitive or accessible for deaf survivors and because the deaf community has historically misunderstood or minimized the issue (Rems-Smario, 2007)
(I've met Julie Rems-Smario, she's very cool.) (I could probably put you in touch with her for a more authoritative answer?)
