We are at war, and we know who the enemy is.
One might also quote those who declared it a good idea to concentrate Japanese Americans in camps to prevent a possible fifth column on the Pacific coast
I'd point out that there were no fifth column attacks on the West Coast.
The fact that similar measures were not enforced against German Americans members
Look into what was done to the German American Bundh sometime.

“We are at war, and we know who the enemy is.”
If we know who the enemy are – based on intelligence, rather than racial stereotyping - we can target them specifically, but there is no place for rounding up entire communities because of the actions of a few individuals.
“I'd point out that there were no fifth column attacks on the West Coast”
You will find people on the left using the same logic to argue that it is the availability & mass ownership of hand guns that creates the death by gunshot statistics in the US. Your line of argument would endorse that point of view and a host of others, as well.
“Look into what was done to the German American Bundh sometime.”
The German American Bund was monitored and individuals were arrested, but there was not a wholesale rounding up and concentration of German Americans in camps. Whole communities were not shipped to the mid-West from the East Coast. It is not comparable and frankly a facetious suggestion. You also ignore the fact that the most highly decorated regiment of WWII was full of Japanese Americans, fighting for the United States. So much for the fifth column.
