Off hand, I can think of no better example than yours of the kind of reasoning that makes the empowerment of demagogues possible . [I added underlining to your quoted post above, as it seemed appropriate.]
Pie: Do you unreserved But calling the duly elected president hitler is reasoned debate? We have had eight years of an unqualified demagogue race hustler as president, so please spare me your patronizing lectures.
No of course not. Calling the newly elected president Hitler would not, in my opinion, be "reasoned debate." I don't know anyone personally that has referred to Trump as Hitler but I understand that some have. I pointed out that there are a few obvious similarities between the two men. These are characteristics of the two men that would be immediately evident to anyone. Do you know what the word "demagogue" means?
