If Hillary had won, it would have also been "antidemocratic" according to your definition. So would you have protested that too? No one was going to get greater than 50% of the popular vote in that election.
Apparently there's some reality there you don't like either.
You Americans are seriously lunatic reality-deniers. Close to 50% of the voters vote for Trump, but because it's not mathematically 50%, you dismiss it as a not-significant part of the electorate. You liberals are no better than the people who stormed the Capitol; you're just as unbelieving of reality as they are.
