A recent survey conducted by the Pew Research Center aimed to examine political polarization. It asked Americans whether they would be disappointed if a close family member married someone of a different race, country, political party or someone who doesn't believe in God.

Less than 20% of Americans said they would be unhappy if a close family member married someone from the opposite political party and only 11% said they would be upset if that person was of a different race.

But 49% of Americans said they would be disappointed if their family member married an atheist, making nonbelievers by far the most stigmatized group in the survey.
