Competing to have the public want you to represent them. How is that not competition? Competing to have a greater majority consider you a viable representative.
With that definition of competition I suppose even a burglar is engaged in "competitive activity", "competing" against other burglars.
A majority enslaving the minority is not "competition" in any reasonable meaning of the word. Competition means A doing their thing, and B doing their thing.
You say enslaving when there is no enslavement. A competition requires A andBto be doing something against one another. It isn't competing if the actions of each are not related.
Look at the real world. Do you really need me to give you a lesson on constitutions? Judges shoot down laws that are unconstitutional. Judiciary over rules the government.
Yes... I've been jumping back and forth between national and global discussions. That said it would be the same as in all western nations. A court would overturn unconstitutional laws.
