And why should I ask them to remove it? It stands there as a testament to the dangerous beliefs espoused by a truly evil person. The moment that we pretend that true evil does not exist and go about expunging it from public view on the basis that one person, to wit yourself, takes offense and/or embarrassment at the fact that an evil man's beliefs about the union are virtually identical to his own, is the same moment that we allow that evil to triumph. I quoted Hitler and I quoted Marx for the very reason that they were evil men who espoused evil beliefs that some people, of late, have become a bit to friendly with in their repetitions of the same. Your buddy #3 just got the boot for being a neo-nazi. That you come along not two weeks later and start espousing a political philosophy that, as both LG and myself have show, is identical to Hitler's is accordingly both disturbing and in need of being pointed out.
Your argument is also morally bankrupt, but that is another issue.
