I don’t think the author was attacking Eliot personally, rather demonstrating the acceptability of antisemitism by his contemporaries, that his sentiment was in the cultural mainstream. The Oliphant cartoon differs only in that though there’s been significant protest, Jews as Nazi butchers is perfectly acceptable in some quarters. His personal views are largely irrelevant.
I agree to a point.
Eliot was a creature of his time, not openly hostile and malicious, but prone to statements at one time, that embarrassed even himself, later in life.
