Why do the proton and electron have equal and opposite electric charge?

Well I guess a mathematician could do a better formulation of the question, such as a verbose expansion of "what axioms grant that the...

As you know, a U(1) can have any charge. Charge is just a number. In SU(N) charge is a matrix. Because Q = I_3 + Y/2, the question can...
