There are others but this is a good place to start
Why is it hypocrisy? The reason Christianity was invented by Roman Emperor Constantine in 300 AD was that he had concluded it would be a far more effective tool than the traditional polytheistic Roman pantheon, a tool for mollifying the masses and making them more compliant servants of his authority as he expanded the reach of his empire. It continued to serve the same purpose even now. The only real difference is that instead of being a tool for geographic expansion it’s is now a tool for pacifying the masses while their wealth is stolen, not their land.
Jesus never existed. God never existed. But Constantine did such a thorough job of elevating an obscure fringe cult into an organized state sponsored religion that people still think the bullshit is the truth.
Edit: Before you give me your down vote ask yourself this: are you responding because you are to weak to tolerate having your assumptions challenged? I realize this claim might be upsetting. But are we just here to confirm our preconceptions?
Edit two: please notice that my underlying point motivating this post is being ignored. My deeper point is that there is absolutely no hypocrisy in supporting Trump and being a Christian because both are the result of an intentional effort to make people believe nonsense and be more compliant to the powers that be.
