Regarding the Florida pastor (of a "flock" of 50 or so) who has grabbed nationwide and even worldwide over his plans to burn copies of the Quran this weekend:
There are worries that the planned book-burning could incite more violence against Americans abroad (both military and civilian), but let's be honest here - the sort of people who will judge all Americans by the worst example of one are the sort of people who don't really need an excuse to hate.
In other words, people who are non-American versions of this pastor.
Bottom line regarding what the pastor is threatening to do:
It's reprehensible, hateful, ignorant, spiteful and worse.
It's also free speech.
