Howdy Anastasia, there was a time in American history not too long ago when Catholics were discriminated against for their religion. This was partly a result of the prejudice and fear people had in response to immigrants from Ireland and Italy. John F. Kennedy was the first Catholic president in the country’s history. The current president, Joe Biden, is also Catholic. So things are definitely different these days. However some Protestant denominations do continue to be hesitant to accept Catholics as “real” Americans.
