I agree.
While I would personally be quick to say, "That's great!" when a deaf person is dating a hearing person. But deep inside, a million things will run through my head telling me of all the ways the relationship will fail. What most of those things have in common? Communication.
I do know a few deaf/hearing relationships that turned out to be great. Those relationships were between hearing CODA and deaf or hearing interpreter (who spends 90% of her time with deaf people) and deaf. I even had a hearing interpreter at RIT who married a deaf guy. They've been married for almost 10 years now and I think they have 2 kids already. Never seen them happier. 
If the hearing person complains about communication and doesn't bother trying, then... forget that person and move on!
