I still don't understand what brexit even means. My understanding of the EU doesn't support the idea that you would just walk in or out of it. When I first heard the term brexit I thought it was the dumbest word for anything ever, and I have not changed my mind about that.
In terms of what is worse... if you go by dead kids count, it's Trump. If you go by normalizing racism and turning the country into an autocracy, again: Trump. By trillions in national debt gained for no reason: Trump by a mile. By coddling of dictators who run concentration camps: that's another notch for Trump! By praising genocide as a show of strength: add another check for Trump there little Billy! If you go by who's fatter and more retarded: that's a slam dunk for Trump.
