Come on now, TQ. You can do better than that. There has actually been new historical research done on these events in the past 113 years
This alleged execution of 2,000 is unfootnoted and is given no primary source.
It's a bald assertion. Where did Fiske get this number? The same place he fabricated his 75,000 Dutchmen - a number which even he agrees is exaggerated?
The fact is, the population of the Spanish Netherlands was probably not even 2 million people in the XVIth century. Are we to believe that one out of every 25 adults was burned at the stake?
The numbers casually thrown about for religious executions in medieval Europe are almost always grossly exaggerated.
As for the proportion you mention, it is by a lot smaller than the killings of the XX century (in Russia and China, for instance).
Anything can be dismissed as anti-Catholic propaganda. At the same time, I found the ending of the Catholic ENcyclopedia article rather interesting: the Albigensian "herecy was finally suppressed by ..." (I do not recall the year). No regrets even 800 years later. Thank G-d; it was menace; it was hard to get rid of; we finally did it.
