Well, even if you date with a deaf partner, remember that some deafies come from hearing families. So you still have to put up with their hearing families too. It is not perfect world either way, deaf or hearing partner.
My last bf did not want me to come with him to celebrate his birthday at TGIF, because he was afraid how communication would be like with his hearing friends. It really hurt my feelings, and I told him that it should not matter. What's important is that I am there for him on his birthday. So, yes, there are some hearing ppl who will treat you as not normal, just because you are deaf. Still, there are some hearies who treats you normally.
That is why I prefer small groups, so that it is easier to communicate with everyone. If it is more than 10 ppl, it is kind of awkward.
