Now Lily, let's not get all wee weed up. I was merely pointing out similarities in governance philosophies between the different groups, nothing more. I doubt you could accuse any of them of being in favor of limited government, state's rights and low taxes. Obviously some have more efficient killing machines than others, and target different segments of the populace. Jews, Kulaks, unborn children, hey, that's diverse!
As for ad hominem attack, that is defined as an attempt to link the validity of a premise to a characteristic or belief of the person advocating the premise. An example might be: "Thatcher was despised when she left office, thrown out by her own party. She never once won close to a majority of the popular vote in the UK."
