Some people don't know what things were like 20, 30, 40, 50 years ago--why should they have an idea what they were like 200+ years ago.
I'm not sure how many people remember that Kennedy was criticised for being a Catholic during the 1960 presidential campaign.
That said: check out this poster.
About 5,000 copies of this flyer were distributed around Dallas in the days before President Kennedy’s November 22, 1963 visit, accused Kennedy of a range of offenses, from being “lax” on Communism, to “appointing anti-Christians to Federal office,” to lying to the American people about his personal life.
The poster was designed by General Edwin A. Walker, a Texan who served in World War II and the Korean War, who had resigned from the Army in 1961 after a Kennedy-ordered investigation found that he had violated the Hatch Act, which prohibits federal employees from engaging in political activity on the job, by distributing John Birch Society literature to his troops. Walker then moved to Dallas and became a leader of right-wing activity in the city.
