When does speech become incitement? It depends on where you live: Brooklyn, Portadown, or Quebec in 1970.
Do we live in a free society? I'd say in this country yes, at the moment, and even these days the occurrence of anything that could be called incitement is minimal. But America is not Europe, and muslim immigrants are not living here in isolated racial pockets to be mocked by condescending white boys with fountain pens. Freedom of speech is the result of a very specific sort of social contract. Does the European contract include the muslim population? I don't know.

Josh Marshall misses the point twice, the second time in a link at the bottom of the post. I'm not a fan of Hamas, but neither am I a fan of Israeli generals; and the former are more capable of pragmatism, or of being made to undertand it.
