Thanks a late night spell check after a long day put ideologue in place of ideology. You expressed my thoughts perfectly
****************
Your post was clear. The questioner was simply being willfully obtuse or was blissfully unaware of perhaps the most significant aspect of the 20th century.
Your point was spot on accurate as well. If the questioner truly did not know what you were referring to, that person needs to get hold of any Robert Conquest book to start learning the dominant theme of the world, 1918 - 1978.
Cheers.
Thanks
