You felt virtuous because the group was pure. You did not notice that the purity was measured by who was missing.
Also known as Othering / purity spiral
A movement defines its good in-group by naming who must be excluded, distrusted, or purged. The leader benefits because belonging becomes conditional on obedience. The cost is that disagreement stops being disagreement and becomes contamination, something to be cleansed, not answered.

You did not notice that the purity was measured by who was missing. The missing people were not gone because they left. They were gone because they disagreed. The disagreement was the contamination. The cleansing was the belonging.
A group can have real membership standards and boundaries. A church that asks members to affirm a creed is not purity framing. The pattern requires that virtue is defined mainly by exclusion and that ordinary disagreement is treated as moral contamination requiring removal, not engagement.
One of these two real scenarios is Purity framing. The other is a different pattern entirely. Which one is which?
The tell
A group can have real membership standards. It's purity framing when virtue is defined mainly by exclusion and ordinary disagreement is treated as moral contamination. A church that asks members to affirm a creed is not purity framing; a movement that purges dissenters as 'impure' is.
A group has real standards and a real reason for them. Someone falls short in a way that is easy to name, and naming it is rewarded.
Because the exit costs you everyone you know, and the group has explained in advance that anyone who leaves was never one of them. Staying requires only agreement, and agreement is cheap right up until the standard moves.
The standard was never a fixed thing anyone could satisfy. It moved inward at exactly the rate needed to keep producing examples.
Field notes where this pattern was identified:
How this pattern gets misused
Someone calls any membership standard or boundary 'purity framing' to avoid accountability. The vocabulary becomes a shield against criticism: any rule becomes contamination.
What it looks like when you're wrong about it

Not sure? Describe the situation to someone outside it. If they do not see the pattern, pause before you name it.
Duty weaponization
You called it your conscience. It was a leash. They handed you an obligation and called it your character, so refusing felt like failing.
Unity simulation
You heard 'everyone agrees' and stopped checking. The agreement was asserted, not shown. Your silence was counted as a yes.
Concern trolling
They said they were worried about you. You knew it was a knife. You let it in anyway because the wrapping made it look like care.
The name is designed to spread. The hook is designed to stick. If you recognized something, share the name.
