Why does he have to say it? Because there are jerks out there who will dismiss his actions as virtue signaling. He is stating it is personal and he is committed.

Do complain this much and call it virtue signaling if someone says they served in the armed forces and they love the flag?

>Why does he have to say that he's married to a black woman. That he has a black child. That he is quitting. That he's hiring a BLACKKK person etc. Just do it man, don't make a wave.

Because he's trying to make a statement that racism is wrong, and because he wants the reasons for his resignation to be publically known, of course.

Isn't that obvious?
