Funny how people tend to say "that's fascist!", "that's like Hitler!" or "that's communist!", none of which has anything to do with the subject (an irrational person demanding death or castration for an entire class of people).
What those phrases do have in common, however, is what is known as "appeal to emotion", which is a logical fallacy.
Maybe I should've spelled it "phallacy"

...at any rate it illustrates a similar emotion-based thought process, rather than reasoning things out. Fairly common in the world of humans, I'm afraid.
