If you can't wrap your brain around why his statement, unwittingly, revealed just how racist he is then we're done here. Get triggered much, snowflake? Does it hurt your feelings when they call you names? Do you whine to your teacher that life isn't fair and they're picking on you?
Yes, Michael Moore is a frothy mouthed liberal sycophant who is suffering from a severe case of TDS.
My guess is, you can't offer a defense of his racist statement either. All you can do is get hung up on the term libtard and comment on that. Figures.
