Also, you’re saying “100 years earlier” as if that’s a long timespan in history. I know, the USA is not much older than that, but in Europe, 100 years is nothing.
And considering that ~40 years after the last Russian pogroms there was this thing called “the Holocaust”, I’m not really convinced that antisemitism was a thing of the past in Western Europe either.
The cited persecution of Catholics was and is still undoubtably, but it things happening around the turn of the 20th century in Britain really weren’t of the same nature as what was happening in Russia, not at all. British weren’t raping and killing Catholics in massive waves of concerted violence with state involvement and approval and that’s exactly what was happening in Russia around that time. 100 years is relatively short time but I definitely argue that a lot has changed and the level of violence is declining. Pinker has some good article on the subject of violence but which notably don’t say anything about violence toward small groups, though say a lot about the larger picture.
