One of the best things I’ve seen on the Internet in a long time is Andrew Klavan’s recent video “I’m Angry, So I’m Voting For Donald Trump.” In plain words, with humor and facts, it cuts to the heart of what’s really going on this election season.

I can’t improve on Klavan’s performance, or even match it, so let me simply point you to it. Please watch it right now, then share it with some friends.  (I can wait.)

Terrific, isn’t it? Klavan’s key point, apart from pointing out all the nastiness, contradictions and flip-flops that have characterized Donald Trump’s campaign so far, is this one: “I don’t make very good decisions when I’m angry.” Neither do I. Do you?

In the cold calm of reflection, are we really proud of all the times we flipped off other drivers, angrily hung up on poor, down-on-their-luck telemarketers, or made cutting remarks to a spouse? How about the ways in which we’ve treated helpless children, or pets? Or persistent homeless people who pestered us on the street? In the daily press of busy-ness and the stress of postmodern life, it is all too easy to treat other people as less than human, if only for a moment. But in such crucial moments, we can do genuine damage.

What should we think, then, of a presidential candidate who brandishes his anger — undiluted and uncontrolled — against anyone who criticizes him? Against journalists who do their job and ask him probing questions? Against other candidates who are doing their job by critiquing his policies? What do we think of a candidate whose first resort is always to an ad hominem attack on the looks, personality, or even current poll numbers of his rivals?

Well, first of all, let’s admit it, we think he is funny. We think it’s kind of cool, the way we applauded the prankster back in grammar school who filled the meanest teacher’s seat with shaving cream — then proudly accepted his punishment, getting scotch-taped in his desk with his mouth taped shut for the rest of the day. (Yes, that was me, and the other kids did applaud.) We enjoy seeing a rebel flout the rules.

But isn’t it less funny if the prankster targets not the teacher, but one of the special-needs kids? That’s even more outrageous, of course. It flouts “political correctness,” if you want to call it that. But is it “brave”? Seeing a strong person pick on the weak … that turns our stomach a little. If we go along with it, even enjoy it, we feel kind of dirty afterward. And so we should. That’s how a lot of Donald Trump supporters are going to feel someday. They need to feel it sooner, before they vote.

Yes, as St. Thomas Aquinas taught, there are legitimate uses for anger. We wouldn’t want to condemn Our Lord for His harsh words against the Pharisees, or His cleansing of the Temple. If uncontrolled or inappropriate Wrath is a deadly sin, it has an equal and opposite sin: not getting angry when it’s appropriate, not caring enough to fight for what is good. Aquinas called that “Servility,” since it amounts to pretending that you are a slave — that you’re helpless to fight against evil, and so you are off the hook. Christian voters who yawn and say that a critical issue such as abortion or same-sex marriage is “settled law” so we should “get over it” and move on are wallowing in Servility. So was Angela Merkel when she opened Europe’s borders to a million unassimilable Muslims.

So we shouldn’t condemn Donald Trump simply because he is angry. There are legitimate causes for anger out there, especially among white working class voters. I personally get angry when I hear “establishment” GOP candidates trot out the same exact policies they’ve been touting since George W. Bush on foreign policy and immigration.

Real political correctness is evil, when it protects leftist demagogues from free speech that challenges them, or prevents conservative speakers from exercising their First Amendment rights at a college campus.

Many voters feel that America’s elites have either written them off or taken them for granted.

On each of these issues, a candidate might be right to channel a little anger. But after that, he’d need to come up with rational proposals that are fair to all involved, that push the needle of justice back towards the center, and rectify real evils.

What is the real evil of a handicapped man working as a reporter? Of a woman of reproductive age (who hence menstruates) asking Donald Trump probing questions? Of candidates who are behind him in the polls continuing in the race and appearing at debates? Of a former P.O.W., now a senator, supporting a different candidate?

In each of those cases, Donald Trump launched vicious personal attacks, and went for the jugular. He didn’t challenge those people on their strengths, or answer them on the substance. He went for their weaknesses, and mocked them for being at one point or in some way helpless. But each of us is weak in some ways, and helpless at some times. Trump scorned them for being human, as if he thought himself, well… a god.

And I don’t want someone like that exercising god-like power, with his tense hand sitting on the nuclear button, with the power to order soldiers to break the law by killing civilians and torturing prisoners (two things which Trump has already promised to do). I don’t want a man who jokes during the campaign that he could kill people with impunity becoming commander-in-chief, with control of the CIA and the NSA. It isn’t wise, and it isn’t necessary. Trump isn’t even consistent in the policies he promotes, just in the mood he encourages. And it’s an ugly mood, that can take us and our beloved country to some dark and dangerous places.
