The first is a (totally legitimate) dig at DEI policies, has nothing to do with racism; the other two need to be put in context, as he was reacting to a poll according to which a sizeable proportion of black people disagreed with the statement "it's ok to be white".
Now, someone who disagrees with the statement "it's ok to belong to " is usually called a racist. That's if we stick to the default meaning of words, without second and third guessing what people really mean to say when they deny it's ok to belong to an ethnic group. I think it's legitimate to be upset in this context and at the normalisation of such a thought, even to the point of reacting offensively.
