They are. They are extremely racist and hateful too. It's mostly Filipinos -- at least in the terminal where my parents fly in and out of. My mom, an attractive white woman, older but not elderly, is always hassled. She'll sit there and watch and only white women are dragged out of the main line.
I've had some fine affirmative action types in other airports paw through my stuff without any gloves (so I had to toss my LEGAL, expensive items since they hacked into them) and puff up their racism in my face.
I’ve found the Filipinos to be very polite. The (obese) black females are Racist! with a capital R. They do not like white females and they never pull blacks out of the line for their invasive searches. SOBs.
