One could speculate on how deep the act actually is here. One recurring feature of the Clippy character is that he attempts to mimic human social behavior in crude and clumsy ways. Maybe Clippy noticed how humans throw accusations of "racism" as an effective way to shame others into shutting up about unpleasant questions or to put them on the defensive, and is now trying to mimic this debating tactic when writing his propaganda comments. So he ends up throwing accusations of "racism" in a way that seems grotesque even by the usual contemporary standards.

Whoever stands behind Clippy, if this is what's actually going on, then hats off for creativity.
