Are you going to pretend that some Jewish people don't look different? Some people you can look at and realize immediately are Jewish. Are you going to look at Sandra Bernhard and think, "oh, I wonder what her ethnicity is?" Now, I can clearly look at her and see that she is obviously Jewish. Since I am continuing with this example, I should note that I have nothing but respect for Judaism, since some people cannot separate visual observations from genocide.
Clbuttification isn't the problem. It is not a value judgment; it is realizing that ethnic groups often have features in common. It is silly to mix the idea of simply recognizing a difference and the separate phenomena of racism. I don't see why anyone should be afraid to realize that people LOOK different. Noting that someone has a facial structure, nose, etc. that stands out as specifically ethnic is not the same as practicing genocide and doesn't automatically lead to it. Making an observation and becoming Hitler are not one and the same.
The people freaking out about the original post seriously remind me of the Californians that are afraid to teach about the Alamo for fear of offending the Mexicans. You can't ignore the obvious because you want to pretend it doesn't exist.
