Wow, you went from "expensive" to racism. That's quite a logical leap. The real problem sounds to me like the Bigfoot crackpots don't want to put their money where their mouth is, so they just whine about the cost and "stigma" (as if it matters) instead of just ponying up the money to get the test done?
Maybe Jerry Springer can help with that?
The stigma matters because scientists won't test it.
