"I'm just telling you what they think--or at least, what they say they think. "

And there's the key....of course folks who intend to discriminate and to violate the point of laws, if not the letter of the laws, will provide some self-serving rationale! They 'usually' (these days) don't just say "I hate all X & Y groups, and I intend to stop them any way I can."

There's always some indignant description of their 'enemies' as interfering with their 'rights' and blanket, unprovable accusations of 'secret controlling bankers' and 'tri-lateral commissions' and anything else they can dream up!
This in NO way shows that we should design programs to reflect inherently biased views.
