I don't know a whole lot of creationists, but we had Michael Behe come to my college and speak on intelligent design. A whole bunch of evolutionists showed up and asked him questions -- behavior you obviously consider MOBBING.
That is an appropriate forum for that behavior. The man came to a college event to speak and presumably take questions - am I correct? Are you suggesting the only questions allowed should be pro-creationist/ID? Now, a docent in a museum is not there to defend an entire belief system/theory/point of view. She's there to show people around the museum. Do you not see the difference?
Don't know if you noticed, but there is a difference between a docent explaining museum exhibits and a college presentation.
