Agreed. Do not give an inch to the Islamists. Not one inch.
They are like Hitler and his Nazis. They do not respect nice people. They do not observe contracts or written documents that they sign. Lying is part of their culture so they "keep their word" at their own whim. They exploit weakness rather than protect it. "Collegiality" is not part of their lexicon.
We will be fighting them soon. It will be World War IV. And it won't be pretty.
