Fox Redux--Should Brian K. be fired for the racial hatred displayed in his recent comment or just for his sheer stupidity?

Just Google Kilmeade and “other species” to get the complete text, but to briefly sum up. In response to a 20 yr. Swedish study that found less incidence of Alzheimers among married folks, he said it wouldn’t apply to U.S. because the Swedes are “pure” while we go around marrying other ethnicities and species.

He did issue a rather tepid apology to keep the PC police off his back, but I get the impression he still doesn’t quite comprehend why some people would find this so offensive.

Evidently this little inbreed is unaware of the basic fact that interspecies sex doesn’t produce offspring and Hitler’s theories were disproven by history.
I’m not really sure which other species were being referenced, but….

What kind of strange breeding produced this little dimwit? All guesses welcomed.
