It's very obvious that Illusionist is an easier career for a deaf man since illusionists rely on people not noticing what they are doing while they put on a distraction with their voice or with a presentation elsewhere (away from the hand that is hiding the other object). A deaf man can also begin to notice how an illusionisy is completing his illusions during the show, creating interest in the deaf man to become an illusionist himself because he feels intelligent that he was able to notice the performer's hidden actions easily.
However, if you meant "magician" instead of "illusionist", that is bigoted yet again, to claim that " more deaf people then you think are a magician". Deaf Is Not A Personality. It is extremely obvious that any deaf human being can be a member of or a believer in absolutely any religion that they want to be in or were brainwashed into, and there is absolutely nothing whatsoever about a deaf man being a witch\magicians\wizard, a priest in Voudon, an Orthodox Xtian, a shaman, an Azraelite, a Rastafarian, or any other religion.
