No. You don't get to dismiss those that didn't vote. It's like everyone wants to ignore the Law of Large Numbers when it comes to elections. The cold, hard truth is that even if we had 100% turnout, Trump still would have won. You seem to think that every non-voter was a potential vote against Trump, without stopping to consider how many would be a vote FOR him.
The Law of Large Numbers means that yes, over 50% of the country wanted this. You don't get to say it was only 30%, and treat the non-voters like a single bloc that would have voted differently. And I get it. It's comforting to think that it's only a third of the population that are full of hate and pants-shittingly stupid. But its well over half. American citizens are fucking idiots, and that's not an unfair generalization to make.
