That seems so american centric.

Like im white and canadian, which is basically the same culture as america, but like a quarter of these seem specificly american to me.

And a bunch seem rediculous to apply as "white culture". Like that your intent matters when it comes to morality. I can appreciate that different cultures fall differently on the spectrum between outcome vs intention, but i highly highly doubt that white people are the only ones who give primacy to intention.

The white people value rationality part seems straight up racist.

But this doesn't say what you said, and isn't a "racial sensitivity guide" for employees.

The phrase "punctuality and logical objectivity (were|are) "white expectations" not to be applied to persons of color" does not appear anywhere in that image, nor does any assertion of the kind.

It's just a (somewhat stereotypical - "bland is best," really?) list of the aspects of Western culture which the author believes derive from "white culture." It doesn't even present these points as negative.

If one were to criticize it, one could point out the degree to which many so-called "white cultural" ideals were founded on a religion not created by white people (Christianity) and non-Judeo-Christian (Greek and Hindu) philosophy and ideals. The European cultural complex didn't arise in a vaccuum.

Also that many of those bullet points seem to be so vague as to be universal. For instance, I doubt white people alone recognize the existence of cause and effect, respect for authority or patriarchy.

But the general premise - that the constructs of white culture (to the degree that it exists, which itself is debated) are considered default in American society, as a function of white supremacy reinforcing that default on all races and suppressing cultural variance in the name of conformity to a white-derived normativity - is correct.
