She has never struck me as particularly bright. However, to state that white races - in particular Jews and Roma - suffer some kind of lesser form of racism than people of colour, is historical ignorance on a jaw-dropping scale.
In the last century alone 6 million Jews and 200 000 Roma were murdered because of their race.

Diane admits these groups suffer some level of racism, but not the hardcore stuff of the people of colour. Theirs, instead, is more like "being a readhead".
This is what happens when groups and people who don't actually care about abstract concepts like human rights, womens rights, racism etc (although say and I am sure to some extent believe they do) rub up against other groups.
It is at this point what they really are is revealed.
What such people care about is the one issue that affects them, and those closest to their group. Same with trans activists who don't extend the same freedoms they shout about to biological women. Same with Greta not giving a damn about the millions in poverty who would be further impoverished by her ultra green policies.
Many of the people who present as the most liberal and "good" (some of whom win Nobel prizes) are in reality the most narrow-minded and tribal.
True decency and consistent respect for and application of liberal values and the sanctity of human life, is vanishingly rare.
