No, it isn't semantics; more people voted for Clinton, therefore there is no silent majority voting for Trump; that is a fact. Yes polling overlooked a big chunk of people who voted for Trump, but that chunk is not a silent majority by any stretch of the imagination.
Is that a real question? Because do please show me where I'm insulting 50% of the country. Are you claiming that me saying they aren't a majority constitutes an insult? That's pretty bold, yet that's all I've said so you really can't be referring to anything else.
