Yeah, we need to stop respecting the "pastor" title. It's so often self-granted and there are no qualifications or prerequisites. Anyone can call themselves a religious leader.
The word "pastor" derives from the Latin noun pastor which means "shepherd" and is derived from the verb pascere – "to lead to pasture, set to grazing, cause to eat".
And God's allegiance is with the weak. Christians can engage politically, but as in all things it should be an act of love, for the weak, for the poor, for the needy, for the "lesser".
But things like "Christian Nationalist" is a painfully absurd oxymoron.
I looked into him. He's not a pastor anymore and doesn't have any leadership role at any church. He does have a Christian business but I couldn't look up if it's a registered 501c3 but they have a patreon.
That's simple, you take a dash of hypocrisy, a gallon of ignorance in your religion and top it off with just enough cognitive dissonance so you don't bleed out your ears when you think about it...blam one Christian fascist ready to go.
