The Quakers should have given up 150 years ago. That was the date of their first major effort in pacifism. More than 200 Northern Quakers went to the South to encourage their brethren, their ‘Friends’ to give up slavery and avoid the coming Civil War. They failed but they continued as a religious order, just like every other religious group that history proved wrong..
From 1960s onward Muslims began moving into Kosovo from neighboring Albania. By the 1990s they controlled two thirds of the country including the capital Pristina. It was clear that the Serbs who had controlled the country previously intended to retake it.
A Quaker, David Hartough, set out to train the Kosovan Moslems in nonviolent resistance. After five years of training, the Serbs invaded the country and drove all of the Moslems out. It was American bombing of Serbia that allowed the Moslems back into the country not their pacifist training.
Quakers failed again on a big scale.
Today the Quakers have decided that Palestinians are the latest version of the Northern abolishionists and Muslim invaders and that the Israelis are the enemies of peace. Another step in the long Quaker history of pacifists getting things wrong and backwards.
The Quakers have no organizational structure. They have meetings and they all think pretty much alike so they don't need much structure. They just go with the flow and the flow is usually pathetic.
Unlike the Presbyterians who have organization and a global campaign of Jew hate the Quakers just have a local individual direct contact with God who tells them to hate Jews.
