My wife is terrified of snakes, I keep mine in a climate controlled shed in the back yard. Her fear is never going to be cured, she doesn't want to be cured. I don't push the issue, I respect her fear and we don't have problems. I share this because it is important to understand some people are very sensitive!
I do snake shows all the time at the local elementary school. If you have no fear and are super excited as you tell them how cool and harmless they are, you'll be surprised at the numbers of people who will get excited about them. I think the best way to help skeptical naive people to open their minds is for them to see others get excited about them. Be excited!
