It happens all the time.
My post about Chelsea Clinton getting attacked was this escalation:
1. Rep. Omar attacked moderate Dem support of Israel
2. Chelsea lightly attacked Rep. Omar
3. Progressive students vigorously attacked Chelsea
and add:
4. Lefty pundits attacked Chelsea
or progressive students, depending on where they sat
All the time. I'll try to find more examples.
The intersectional identity politics wing is practically designed to be in a constant state of attack.
