Not getting this is part of how you get people insisting that right-wingers aren’t “real Christians”, which lets them off the hook and erases the real harm that form of Christianity has done
I don’t like those people, as a Christian I have very little in common with them, but they’re Christians too
But seriously, dismissing Christians who commit harm as "not real Christians" is the same kind of defensive fragility as some white folks have who refuse to learn about and learn from their racial legacy. It's nescience all the way down.
Heck, I’d argue that dismissing “bad Christians” is a poor excuse to avoid the hard work of rebuke and correcting that followers of Jesus are called to participate in. “We don’t claim them” is a cop-out.
