Walker Colt,
Thank you for your input, but I honestly feel that simply describing the conditions of the time is not an answer. It can not be as simple as monkey see, monkey do, but you are correct in that some of the "greatest" men of those times held slaves. But there were those who openly challenged the practice... for example my personal hero John Quincy Adams... who as you know challenged Freemasonry and Manifest Destiny... and obviously slavery. "What can I do for the cause of God and man, for the progress of human emancipation, for the suppression of the African slave-trade? Yet my conscience presses me on; let me but die upon the breach."
The anti-slavery movement in France (the true home of Scottish Rite Freemasonry) began as early as 1789 and they finally outlawed slavery by 1818. The enlightened movement (via Masonic ties) influenced the Mexican government to abolish slavery by 1829, which as we all know gave rise to the fighting with Anglo-Americans in Texas. Why did it take so long for American Freemasons to turn their backs on slavery? It wasn't because "everyone" was doing it and if that were the reason, Masonry should have challenged the practice based on the morality and principles of Freemasonry. This is what I can not get my head around. With all the good that Masonry represents, there just seems to be a underlying historical pattern of self-serving manipulation. Right or wrong, I believe that these examples are what fuel the "conspiracy theorist". When non-Masons today learn of the Masonic role in U.S. government, it is only natural that they feel detached and threatened. I think that the secrecy of Masonry might just be its biggest enemy.
"It wasn't until the 1960s or so before alot of Christian churchs allowed african americans into their congregations." I agree, but this conversation is about Masonry. The shortcomings of the Church is a whole other topic... unless you feel they are in some way connected?
"They looked at all the scientific, mathematical and engineering progress of Europe compared to nothing from the african continent. Europe had castles, roads, bridges, science, philosophy, etc and the africans had nothing compared." What about the discoveries made in Egypt & Ethiopia? What about the cera perduta process? I don't think that the perception of Africa and its cultural accomplishments were as inferior as you make it seem. The enlightened Masons would have known better. Anyway, it was kind of you to respond.
