This isn't a trial; it's a burlesque. There is no jury, but merely spectators.
I wonder if this whole "trial" thing is an outgrowth of ed. schools.
I knew someone in an ed class. One day they were discussing the teaching of some science thing or the other and the instrucor did have the class vote on the correctness of the concept. :-(
FWIW I agree with the boycott. It's set up as a kangaroo court and scientists should not have to be lawyers also.
I teach. When a troublemaker starts up I simply tell them that this is what scientists have observed and concluded. They are free to think whatever they want but the class, nevertheless, will continue to be on what scientists have observed and concluded.
My two cents...
