Not a ton of time, so let's do the easiest ones:

He wants lower and middle class tax cuts.

His so-called plan offers "the largest benefits, in dollar and percentage terms, to the highest-income households." Without massive, crippling cuts across the board (none of which he has specified in any way, of course) he would send the national debt through the roof. Stop pretending he's in any way progressive -- just another Republican working for his ultra-wealthy buddies, and just another politician promising something beyond impossible without the guts to explain how he'd actually do it. (When Trump has to actually offer a specific policy, instead of a vague promise to "do the great thing," it utterly crumbles.)

He is against uncontrolled, illegal immigration.

His plan involves a horrifying Gestapo-style roundup of eleven million people, separating children from parents, tearing families apart, hunting people through the streets of America. Besides being unfathomably cruel, it (and his lunkheaded wall) are utterly impractical, both financially and in practice. Every candidate is against uncontrolled illegal immigration (which has slowed to a trickle, mind). The question is: what is a practical and effective way to deal with the mess we're already in, and the people and families that are already here, in a way that does not wreak a horrific human cost and is best for our country's populace and economy going forward.

Likes universal healthcare, is open to replacing America's broken system with something similar to Canada but better.

"Better." Trump says this sort of thing a lot. "I will do something great!" he proclaims over and over again, zero specifics, and for some reason you believe him. Even though anything that he actually releases in terms of a policy plan is either standard party-line GOP fare or beyond ludicrous (see above tax plan) and destructive. As far as health care, he's said nothing about a universal system, not lately... you're talking about old statement's he's repudiated. Now he just says "I will do the great thing." But no matter: he can just keep saying the words "big," "beautiful," and "great," and you believe him. Why?! Just because he's an "outsider?" So is my fucking goldfish, and it has told a lot less bald-faced and brutally damaging lies.

And yeah, dear God, does he lie. Or if he doesn't lie, he's just insanely ignorant. He has no idea what he's talking about. He gets his information from chain emails and cable-news pundits, spews it as fact, and will never, ever admit he was wrong. He will believe any hoax; he's gullible as fuck. HE'S A FUCKING ANTI-VAXXER. He's obsessed with wealth, celebrity, and polls above all else. He supports torture and physically threatening dissenters. He's literally an African warlord dictator in white skin.

He speaks in enough vagaries, lining up on every side of as many issues as possible, that people are beginning to invent their own visions of Trump for themselves. "Oh, he doesn't really believe that; he's just playing along!" everyone now says. "I believe him when he says the things I agree with, and I know he's just acting when he says the things I don't agree with!" And this has apparently been accepted by everyone from Jerry Falwell to the /r/politics brogressive circlejerk.

So now apparently we're all ready to elect a horrible, horrible excuse for a human being (does anyone really dispute this?) because he is not a politician and because we don't really know what he truly believes. That's it. That's all.

Why not just elect the fucking wino in the gutter outside my bar. At least he probably doesn't believe in unconstitutional religious litmus tests.
