I agree with Will. Usually once someone has actually handled a snake, they're fine with it. In fact most people become fascinated with them after they've handled one. I don't know if forcing is the best method, but hey, whatever works.

I work with people who have a range of interest in them. One actually went out and got herself a BP last week. One is generally fascinated with them. One is gradually getting used to the fact that I keep them. And one is deathly afraid of snakes but has asked if she can come over and see mine in the hopes that just being around them will quell her "unreasonable fear" (as she calls it).
