I don't see where Beck (or anyone else) was doing the latter.
I ignore his religious stuff, even if it sounds good. It is because the only thing “his” god has in common with my God is their name. Their personalities could not be more different.
I focus on his political statements.
When Beck speaks of him Mormon God, it is different than the Christian God.
As long as you know that, it’s fine - just as when a Hindu speaks of his god it isn’t the Christian God, and so if the Hindu calls you to Vishnu, you have a clear understanding of the differences.
Beck’s call to God is blurring the differences. I’m often surprised that so-called christians are offended when someone points out the differences.
