Why is that bad?

>To be clear: it would be equally bad if you swapped left and right in that sentence.

Not at all, if it was swapped, the left would be calling for diversity, equity, and inclusion. They'd call those opposing said diversity, equity, and inclusion initiatives every -ist they could throw, all while playing the victim.

Then O'Sullivan's First Law inevitably comes true and the terminally online leftist entryists shut anyone right of them out. This is where Wikipedia is now.
