I have to disagree with Michelle on this one.
A lot of people feel the way you do.
Interestingly, Malkin herself once found the internment of Japanese in WWII "abhorrent". When she received a flurry of letters from WWII vets asking her to investigate the issue before making up her mind, she did that. She read a book about the MAGIC intercepts.
Her mind was changed.
That is the essence of the book. She doesn't call for the internment of Arabs or Muslims. She is simply saying that we should not be so paralyzed by political correctness in the War on Terror that we put that political correctness before our nation's survival - and that is what is happening out there.
People use the internment of Japanese to make the case that we shouldn't profile our current enemy.
That could be our undoing.
Will it be worth it?
You say this now. If a repeat of 9/11 or worse happens, you'll be thinking differently.
