They weren't there were entire parties like the No names based on anti Catholic bigotry. In Germany the situation was a bit different since Catholics voted as a bloc. Anti immigration there was government policy required to be rubber stamped by a Protestant aristocracy and a Protestant majority Recihstag whose power was in jeoparady if that changed. In US while large percentages of the population would oppose immigration large parts of the country would in terms to actually stop the immigration. That didn't happen until the 1920s which was perhaps the xenith of mainstream American racism.Given the widespread anti-Catholic sentiments in the US, why was the US so eager to allow a lot of Catholics to move to the US in the 19th and early 20th centuries? I know that the US had large-scale Catholic-phobia as late as 1928, when Al Smith's Catholicism cost him a lot of votes during his presidential run. However, this simply raises the question of why exactly the US let so many Catholics move into the country in the first place. I mean, Imperial Germany was also Catholic-phobic during this time but unlike the US it never opened its doors to large numbers of Catholic immigrants. Why was the US different?
