Many of my experiences with the Deaf community have been very positive. I'm not sure if this has to do with the fact that we have a local deafblind center in our area, but the staff of the center does encourage members of the Deaf community to work with DBPs (deafblind persons) who are learning fingerspelling or sign.
When I attended events within our local Deaf community prior to receiving my CIs, I brought along a tactile interpreter who would introduce me to people and then let me communicate with them on my own using tactile sign. If I came across someone who was uncomfortable using tactile sign, my interpreter would serve as the "go-between" me and the other person.
Now that I have bilateral CIs, I don't bring along a tactile interpreter. Instead I go alone or with another Deaf person. If I go with another Deaf person, he/she introduces me to people and allows me to communicate with them on my own.
Having said that, I *have* had negative experiences with some Deaf people. When I attended a lunch social for Deaf and hard of hearing students at my university, no one wanted to sign with me. My captionist went to the socials with me to help facilitate communication, but when I tried signing with others, they would say "hello" and then ignore me.
In regards to being accepted by the hearing, Deaf or blind communities, I would say that I feel most accepted by the Deaf and hard of hearing. Even though I was born blind and have been a member of our local blind community for over 20 years, I've found that many blind people are afraid of my deafness. In contrast, when I speak to hearing people, many of them are frightened by my blindness.
I feel most comfortable with the deafblind community. After I lost my hearing, I had the opportunity to attend an American Association of the Deaf-Blind (AADB) conference and I'll never forget the acceptance and understanding I received. Every type of communication style was welcomed and no one criticized my poor signing skills at the time. 
To this day, I still communicate with the friends I made at AADB 11 years ago.
