If your principles change based on whether it helps your “tribe,” then it’s your tribe you believe in, not your principles.
Christians who talk about religious liberty, for example, but are silent (or worse) when religious freedom is compromised for unpopular religious minorities, don’t really believe in religious freedom.
They believe, at best, in a majoritarian kind of special pleading.
They believe, at worst, in the identity politics of victimhood.
Principles stand regardless of the politics of the moment. If we stand up for the First Amendment when our side is harmed (and we should), then we should stand up for the First Amendment even when our side will be angry with us for doing so.
