1) What? Fact: the electorate chose Trump as the next US president. The fact that most of the country wants what you don't want doesn't make it a tyranny of the majority.
2) I don't care who is on what train, and I'm not shitting on anyone. Fact: OP's grandparents didn't fight for Trump to not be president. That what OP's grandparents or OP want is in contradiction with what the USA got isn't an indication of tyranny. What OP or OP's grandparents want doesn't generalize to what everyone else wants or should want, that's the point, and it's not an insult.
