It’s a dishonest political cudgel:

Notice how companies like Google, FB, etc that advocate “diversity and inclusion” tend to have highly skewed politics, such as harassing and firing conservative employees.

The calls for “diversity” are the exact opposite — a call for cultural hegemony by far left views and racistly color-coordinating the population, so we have “balance” in the view of avowed racists.

The purpose is to bully anyone who opposes their racist ideology by labeling them as “against diversity” — a standard language game from fascists.

You are being gaslit.
