It is interesting to note the overall sequence of the discussion.
A: "N is bad, he did xxxxxxx"
B: "oh really, please tell us about xxxxxxxxx : how was xxxxxxxx done ? how much of xxxxxxxx occcurred ? was it unique that only N did xxxxxx, or was xxxxxx rather common among nations of the era ? was xxxxxxxx apolicy decided upon by N, or a consequence of other actions and events ?"
A: "I dont know those details."
B: "Well, here are a few details that I found ...... (adds some information)"
A: "But your details do not condemn N sufficiently, so you are a ___________ (adds personal insult)"
B: "So, you have really no answers for my questions about your assertion that started this ?"
A: "No, of course not. Everyone knows N is bad, and he did xxxxxxxxx, among his many other evils. You are a _____________(adds personal insult) if you dont immediately agree about this"

One might call this the "algorithm of accusation". One can just change the xxxxxx and add personal insults to taste. Should save some time in writing postings, I suppose.
