I would like some documentation on this. I seriously doubt GW was ostracized by any other plantation owners, at least not after the war. He was far and away the most respected man in the country, and anyone showing him disrespect would have been himself ostracized, if not challenged by the multitude of Washington admirers and shot dead.
He also refused to allow the typical plantation owner hospitality of inviting a male guest to review the young women in slave quarters to choose which one he would take to his quarters and rape that evening.
While this no doubt happened, I doubt it was "typical" or openly practiced. Harriet Beecher Stowe, for instance, appears to have missed it.
You have something resembling evidence.
I think this is in Flexner’s three volume history, but my copies are now in storage in the garage. Could also be in a book titled “The Slave Communityâ€, which is also in storage now. Those two instances were so striking they have always stayed with me. True Washington was highly respected, but he also accumulated a lot of resentment from the aristocratic Southern ruling class. A clear example of that undercurrent of friction would be the 60% compromise that the delegates had to make.
