What they did was comparable to visiting a "learn about Christianity" forum and asking lots of critical questions.
Questioning a museum worker is not sacrilege, and they didn't throw crap.
You people are really unbalanced.
A person that goes to a "learn about Christianity" forum for the expressed purpose of asking lots of critical questions, to the point where the instructor cannot present the material she is supposed to present, would be doing the same thing as what these people did to the museum docent. That indeed would be the equivalent of tossing a turd in the holy water.
The museum mobbers were not there to learn about evolution. They were there to keep the docent from presenting the material. It's nasty, disruptive behavior.
Abusing a museum volunteer for 45 minutes when the purpose of the questions has nothing to do with learning anything from the volunteer isn't acceptable behavior, and anyone employing the 2nd Law of Thermodynamics as an argument against the Theory of Evolution is throwing intellectual crap of the worst odor.
