Yeah, we know. You can look inside the mind of the pilot and know that his hidden motive was that he was a bigot, but the other passenger was NOT a member of the DNC or ACLU or LP with a hidden agenda.
Yes, this gets to the crux of the matter. Did the pilot say something specific to implicate "racial profiling"? If not, how would these passengers be able to know what he was thinking? Sorry, it just doesn't make sense.
