Let's stick to beekeeping. I have demonstrated the handling of bees in a number of situations. One being in front of an Elementery School group at their School which had a bee tree on the edge of the Parking Lot. a swarm had lit on a conifer of some sort in the School Yard. A friend of mine, in our Colonial garb, being employees of nearby Colonial Williamsburg, went to the school and collected the swarm into a modern conventional beehive. The Teachers wanted us to show the children what the queen looked like and to tell them about the bees.
None of them were wearing protective clothing and neither were we. Of course people are fearful of bees. Some of that is a healthy fear. Much of it is imprinted.
Now, I don't think anyone uncomfortable doing so should do what I have done, but telling people that they have to do demonstrations one way or another? I don't go along w/ that either.
I think beekeeping demonstrations w/out protective gear shows people what can be done w/ bees and that getting stung is nothing to FEAR. Besides, what's a sting or two? I demonstrate getting stung too. I also talk to the audience about the defensive nature of bees and how to be around them in a safe and calm manner.
