If it was an unbiased critique of Christians and politics, and trying to suggest Christian churches refrain from politics, it would only be an an honest critique if it most of all was going after not “evangelicals” but the uber Left, uber Liberal “mainline” churches like the UCC, the Methodists, the Lutherans, ect. They are 100% politics more than “Christian”.
I drive past a Lutheran church when I go to work. They are alway flying the pride flag and put up various signs for BLM, Ukraine, “gun violence” and the like. They support the current thing.
