An apology was neccesary because the students apparantly weren't properly informed of what was going on. Moreso if they didn't have a choice in the matter. I'm not sure if this Thomas character intentionally misled the school about the point of the assembly, nor will I implicate him in anything, but forcing others to listen to what you have to say or coercing them to do so, regardless of their wishes, is contrary to the faith such people claim to represent.
