as evidence for what Christianity in the US is like is intentionally misleading
If I was trying to claim that is that standard view, then it would be misleading. Since I was actually claiming that there are a wide variety of beliefs among Christians, some even aligning with your values, it is pretty spot on representation. Treating them all the same is prejudicial behavior.
A fair-minded person would give an individual a chance to act like an asshole before treating them like trash.
