What a load of shite.
Does the green light mean the driver is Irish? Or white? Can't you be Irish and black, asian, whatever? And what about those Irish that have an Irish passport due to their Irish grandparents, bu have never been to Ireland?
What's important about a taxi driver is that they know their way around, get you there safely, and don't rip you off. There's tests they have to pass to show that they can do both of that, if they pass them, what the fuck does it matter where they're from, what their passports say or what colour they are?t
