Yes, it’s almost Biblical. So the joke’s on them!
There are several aspects:
* hair cutting as punishment
often done to women, whether just cutting it short or shaving the head, but now that means they are punishing themselves - which gets to be close to the liberals’ constant “cleanses” as if to expiate the guilt they put on themselves for non-sins and sins they say aren’t
but as punishment, having it short in a society of long hair shows who you can mock/condemn/shun
* hair cutting as a show of grief
makes sense when you’re doing it to rebel/mourn/show how unhappy you are, though it doesn’t have as much weight when so many women have short hair
