Ah. This is all a joke to you. Sorry for having taken you seriously.

May I ask, if someone were to make a gesture indistinguishable from a Nazi salute, what would be necessary to convince you it was, in fact, a Nazi salute?

Ok, not a downvoter, but I’ll bite. A system with more than one party is more democratic than a system with a single party. Are you asking which of the two major parties in the US is the “second” party, making the US more democratic than if there were a single party? If so, I see why no one is answering. If not, perhaps you could clarify your question?
