I don't know if anyone besides me and Ridley read QC, but it's set a world were there are robots all over the place and they have equal rights and stuff. The subject of this comic is bot fighting. If robots who have equal rights, seen as citizens choose to fight in gladiatorial games, why can't they. I don't normally agree with Mai (The blue haired one) but in this case I can actually see her point. Human's wrestle, why can't bots fight?
I don't think that bot fighting is illegal in QC, I think it's more of a matter that the skate park fights are the robot equivalent of an underground fight club. Basically, the issue isn't the fights themselves, but a lack of regulation and licensing.
