The context it was said in made the statement rather jarring. I am all for their initial stance of "no politics" etc, but their all-hands was a face palm all around.
A lot of the framing around implicit bias and white privilege is actually straight up generalizing about a group based on skin color. That's racist. This business that it's not racist if it's against white people is seriously wrong - and racist.
Employees calling the organization 'White Supremacist' is the thing that should be 'jarring' or at least controversial. There are arguments to be made, sure, but the language is fairly extremist.
