Islamophobia or a real reason to fear?

Suppose you had a room full of mainstream Christians. And suppose, at the podium, you had people who were obviously Christian clerics.Now suppose that the clerics asked some very leading questions, worded in a way to suggest that people would be violating their Christianity if they did not respond in a particular way.How do you think those mainstream Christians would respond?

I certainly think that Islam poses a threat. But, in the USA, I am currently more concerned by the threat from right wing Christianity.
