Belloc's The Jews is a nice introduction to this issue. He wrote it a century ago when things were similarly heating up, but before things had clearly boiled over.

He was prescient when he said:

"For if the quarrel is allowed to rise unchecked and to proceed unappeased, we shall come, unexpectedly and soon, upon one of these tragedies which have marked for centuries the relations between this peculiar nation and ourselves."

He was a devout Catholic, had Jewish friends, and devoted a chapter to what was wrong with antisemitism. He was earnestly trying to solve the problem before it was too late.
