Bingo. The people who spout stuff about "licenses" and "no right to refuse service" just want to establish a government state to order people what to do.

Bull. Because if a cab driver was to say that they refused to carry patrons for any of a variety of other reasons - skin colour, religious garb, gender, and so on - it would be called illegal discrimination. Personally, if I was in charge of permits for airport taxi drivers, I would tell them they can either take any reasonable fare (refusing to take a visibly drunk and vomiting person would be reasonable, for example) that shows up at the curb, or not work the airport at all.
