I really wish atheist would just let it rest. Atheisism is now the norm, taught in schools and colleges. So what if a conservative values Jesus as God? It's only got traction in political discourse, not really policy anymore.
And even if it did? So? What is a belief in God going to do? Kill babies? Nope.
Conservatives need to just accept each other and leave the rest to bicker occasionally. Hell, trump is no Christian IMO. I'm still all in. Just like I'm sure you've been with Christian politicians.
I don't really see why an atheist would care? So he believes in God, ok? Policy is what matters.
My opinion of course.
