You chose to ignore that, blathering on about the middle ages is off-topic.
The original comment was entirely arbitrarily limited to the 1900s, and as it brought "the left" into the discussion unprompted, I can only assume this was done intentionally to justify specifically going after left regimes. So firstly, I don't see why a counter-argument should stick to this arbitrary time frame, and secondly, some of my examples do in fact apply to this time frame too.
Like I said to the other chap, I do question the psychological need you have to run defense for the left...
