No argument there, but “in nature everything has an opposite” is just as illogical; many things have no opposite, thus it’s not “at least two” it’s zero asshole gods in a nihilistic atheistic universe, one asshole god in a true monotheistic universe, one neutered god and one not-quite god representing the bit that’s been neutered off in a false monotheistic universe, one good god and one bad god in a morally balanced duotheistic universe (looks identical to the zero god(s) option), or a variable number of variably asshole gods in a polytheistic universe.
