I don't dispute that.
OK.
OK, but please understand that many of those people have failed with oral training and are either jealous or mad at you because they thought you were sucking up to the hearing people. In an ideal world, that wouldn't matter and all people would do both, but unfortunately, some people do get jealous of deaf people who can speak and lipread, and others are just plain mad because it didn't work for them and they're thinking you're sucking up.
I've needed signing and I'll continue to do it with my current gf (she's HoH with declining hearing and doesn't want to risk having to depend on lipreading).
