I'm sorry, but the docent in a museum is not "teaching dogma." She's there to present what the museum exhibits. Period. If creationists have an issue with what the museum exhibits, harrassing volunteer docents isn't the way to express it. These jerks are no better than left-wing "activists" in their approach, and these tactics will not do anything to further their cause.
Stick around and follow this thread. You'll be amazed at how many of them are right here on FR
They remind of the adults (adults!) who wanted their money back when they found that the automatons in the "Dinosaurs Alive!" travelling exhibit weren't real dinosaurs.
The dogma is in the plates and readouts while they tour you around, so he/she is spreading the Evo deal.
