I side with you in theory, in practice we are talking about a nation here which has a creationist museum*, a significant portion of, if not all world's, flat earthers, and a great number of guns. In other words, in a nation with a great number of heavily armed intellectually challenged you have to understand that our idea of freedom of speech is simply not that suitable. I know, I am playing catcher in the rye, again ...
