He's a tempting target, and sure, he's a fraud. Always has been. But, it's also the fault of the ones who allowed themselves to be taken in by a charletan, an anti-Christ.
If they were really devout, they would.have seen him for what he is (and Trump) a mile away. It's not like the bible isn't full of warnings.
Jesus' ministry was a near constant litany of
1. Be good to each other. Take care of each other.
2. Don't follow corrupt people and give them power over you.
3. Don't judge. Keep the religious hypocrisy I'm check. Be spiritual instead.
4. Watch what people do. Don't trust liars and cheats and people who take false advantage. Don't horde anything, it causes suffering.
