People, reading through the whole thread it seems apparent to me that tommy's intention was to say that Tower Records is a bad place, and that Dachau was also a bad place (to use a grotesque understatement, on my part). He was not saying that Tower Records is as bad as Dachau. His argument was along the lines of "Red is a colour. Blue is also a colour." Instead, most people have evidently read tommy's comment as analogous to "Red is blue."
However, tommy, you should be aware that the Holocaust is a uniquely inflammatory topic. This, combined with the flippant tone of your post, was always going to spell trouble. You're an intelligent person, and you should have thought twice in this instance: with a bit of effort, you could have formulated a less upsetting way to frame your argument.
