Islam Is "Peaceful"?

My teacher told me that my comments about Islam and Muslims went too far either directly or indirectly. Once I found an article about a Florida Muslim doctor, I wrote this e-mail tho him:

"I'm almost tempted to say that you owe me an apology, because- like I said- there is a fine line between race and religion; and I'd inter any Muslim now. Keep them all in one place and watch them, because even "moderate" (secular) Muslims could grow terror cells- right even in the camps. So, I think I know what I was talking about when I kept talking about Muslims and Islam versus Japanese Americans and Pearl Harbor.

I might be "close-minded" (re: [a fellow student's] comment), but I'm not stupid. I know Islam/nominal Christianity is different from race or true Christianity."
