@Walter Hinteler,
I'd certainly never argue with that. There was a newspaper cartoonist in New York who has become a "hero" in American history, Thomas Nast. Nast becomes an American "hero" because he takes on the Democratic political machine headed by "Boss" Tweed, the Tammany Hall political machine. Tammany Hall was around from the beginning of the country, but in the 1850s it became the headquarters for Democratic "machine" politics. Nast became famous for lampooning Boss Tweed and Tammany Hall, and allegedly exposing their corruption.
However, what American school children aren't told is that Nast did this because he was a virulent anti-Catholic and anti-Irish bigot. One of his cartoons, which can still be found online but which doesn't appear in American elementary and secondary school text books, shows American children ("good, decent Protestants" every one) being menaced on the shore by crocodiles, which are actually Catholic bishops, whose mitres are the snapping jaws of the crocodiles. Interestingly, Nast did not attack the Republican Party machine, and was silent about any corruption on the part of Protestant, "nativist" politicians. The school children are being threatened by the bishops as a symbol of the demand by parochial schools to receive public funds. The public school is flying the American flag upside down as a distress signal, and in the background is the "Political Roman Catholic Church" and the "Political Roman Catholic School." The Catholic church shown flies a flag with the papal emblem, and a flag with the Irish harp. Note the stout young Protestant boy in the front with a bible in his coat, protecting his terrified playmates from the evil bishops. Nast's vituperation (and he was certainly not alone in attacks on Catholicism and the Irish) ignores that public school systems used a Protestant version of the bible, conducted Protestant prayer sessions in the schools, and openly touted Protestant morality, and taught in the classroom, making a point that it was Protestant in its provenance. Although several different sects joined the Catholics in demanding public money for their schools, including many less popular Protestant sects, by far, the biggest supporters of the call for public support of parochial schools were Catholic.
This was probably the most direct and virulent anti-Catholic cartoon Nast produced. It is possible to be an anti-Catholic fanatic and an anti-Irish racist in this country, and still be counted a hero.
The image below shows Nast's typical depiction of the Irish as simian and threatening, in this case showing an Irish politician sharing the spoil with a Catholic priest:
In the image below, Nast again depicts the Irish immigrant with ape-like features, and pairs him with the southern black (Nast was apparently an equal-opportunity bigo), and the caption for the cartoon was "The Ignorant Vote."
In the image below, entitled "The Promised Land," Nast expresses the belief popular in his day, with Irish immigration and increased immigration by Catholic populations such as the Italians and the Poles, that "Rome" had its sights set on the "conquest" of the new world.
One might argue that Nast was one man, but he certainly expressed popular points of view in his day. His anti-Catholic and anti-Irish virulence certainly did nothing to impair a career which prospered over a period of more than 40 years.
