Last Sunday, a member of my Mormon bishopric stood before the congregation and read a letter from the governing First Presidency encouraging us to take part in the political process even if we are fascists or communists.
The letter didn’t specifically mention those two groups, only that “principles compatible with the gospel may be found in the platforms of each of the various political parties.”
I don’t know that much about communists and fascists, but I’m pretty sure they don’t believe the government should regulate the public use of breathable oxygen. There’s a gospel principle I could support in politics.
