Except the one you are complaining about of course, which came up again in the 20th century when the involved pope was up for canonization.
May I take it you are now acknowledging that a) it happened at least once in the 19th century and b) it happened, and it was indeed a structural part of the churches anti-jewish doctrines, and are now pinning your feeble hopes for this argument on discrediting my timeline?
My knowledge of the event is limited to a bad movie, so I wisely hold my opinion on the subject. You should learn to do the same. I take no issue unless I am certain of what I am talking about. My point is that you indicated that this was a widespread problem taking place frequently in the late 18th Century. One regrettable incident is not evidence of widespread antisemetism, and yes, your timeline sucks. The modern Church began to exist in 1870.
