While Democrats and Republicans are aligned in their views about many belief systems, on others members of the two parties are more highly polarized. The largest gaps are in views of atheism and agnosticism, which each receive net positive ratings among Democrats — more view each one favorably than view it unfavorably — but net negative ratings among Republicans. Democrats are also far more likely than Republicans to assign net positive ratings to Buddhism, Satanism, Islam, Wicca, and Unitarian Universalism.
Among the belief systems that Republicans are more likely to view positively than Democrats are the Southern Baptist Convention, Christianity, the Amish, and Catholicism.
Averaging across all religions, groups, and beliefs polled, we find that the net favorability rating assigned to all groups is similar among Democrats (-3) and Republicans (-5).
