Disagree, Curt. Trump would have ranted about his "second amendment people" "doing something" about the "rigged election." There would absolutely have been protests, and given what actually happened at his rallies, perhaps much more violent protests than we're seeing now. His campaign showed a penchant for inciting violence - why in the world would we assume things would be different had he lost? Hell, even though he *WON*, so much of his public commentary has been to either continue to aggrandize himself ("Mitt called to congratulate me" "Kasich called to congratulate me" "Jeb, George W, and George HW called to congratulate me") or to continue to whine about those who disagree with him ("Professional protestors/media very unfair!" "NYT losing thousands of subscribers because of their poor coverage of me" "NYT so dishonest"). This guy and his followers were going to be noble in defeat? I don't think so - he's been a mixed bag at best in victory!
For however much Clinton is "disliked by the masses" let's not forget that Trump is disliked even more. His favorability ratings were lower, and Clinton is going to end up with at least a million more votes than him. Let's not let the electoral college obscure that fact.
Also think there's a LOT more to current protests than people simply expected Clinton to win. As mentioned before, she's going to win the popular vote by a VERY sizable margin, and many of the people who are protesting feel that Trump is personally dangerous to them. That combination of factors is leading to the "not my president" stuff that you're hearing. Had Trump not called Mexicans rapists or threatened Nazi-style registration of Muslims, had he vehemently disavowed the full-throated support of white supremacy groups, were his comments (to say nothing of the present allegations) about women not so vile, the post-election mood would be VERY different. Millions of voters legitimately FEAR what this outcome means for them. Pundits who want to boil these protests down to millennial cry babies who didn't get their way are painfully and sanctimoniously out of touch.
