The first person that invokes Hitler is automatically the loser of the argument.
Normally that is the case but some of the similarities here are very eary and so I think the analogy is apropo. Similarities, (1) Hitler built a personality cult - Obama is building a personality cult. (2) Hitler controlled the media so that he could define truth - Obama is more and more controlling the media. (3) Hitler gradually subverted the German Constitution and illegally accumulated more and more power in his own hands - Obama is subverting the American constitution and accumulating more and more power in his hands. 4. Hitler did not respect the lives of the unborn and the infirm - Obama does not respect the lives of the unborn and infirm. 5. Hitler devided the people and turned them against certain groups (like the jews) that he scapegoated and blamed for Germany’s economic collapse - Obama is turning the poor against the middle class (which he calls the rich) and is blaming them for America’s economic problems. Obviously I don’t know his end game but the starting positions are earily similar.
