Yes, the "if you don't like it, move" philosophy is silly. Many people simply CANNOT move for various reasons.
The counter-argument that rule-of-majority is rule-of-minority is silly. To the best of my knowledge, no one in this thread is arguing that the children should be forced to read the book -- they are simply saying it shouldn't be removed from the library entirely.
The belief that the appropriate "compromise" between book burning and NOT book burning is to move to a different community is silly. Assuming you invest everything you own to go start some nice little commune of your own, how are you going to prevent book burners from moving in until they reach a majority?
I always find the "majority SHOULD rule" arguments amusing because I live in an area where the majority of the populace now speaks Spanish as their first language. I've yet to hear anyone suggest that all the classes should now be taught in Spanish and the English-only kids will just have to catch up. Funny how "majority SHOULD rule" only ever seems to come up in religious arguments and not, say, cultural or language arguments.
