Rabbi Cooper, you're wrong (as quoted in the Los Angeles Times). I know we all make comparisons to Nazi Germany far too often, but this is a case in which it's appropriate. And though I was uncomfortable saying it loud, I refuse to sit by and not say anything. First, your rights are abrogated based on how you look. The... next step could well be, "All you foreigners who are here legally can wear this badge so we know who you are." It's a dangerous, slippery slope, and if we ignore this just because improper comparisons have been made before and we're afraid to tell it like it is, we're allowing evil to flourish.
