Donald J. Trump is the president of the United States of America. We can, as a public, disagree on many things about him — his policies and his Cabinet picks, for instance. But one thing I hope we can all agree on is that Donald J. Trump does not act like a grown-up, and that's a very serious problem.

The fact that DJT is a child is not some new development. We saw this behavior during the campaign when he talked about his penis on stage and called people names (remember Little Marco?), but so many people, even those who opposed him, hoped that he would act like an adult when he got to the White House because, you know, he's the president of the United States and not the school bully.

Trump has not even been president for a full month, and we are already watching in shock and horror as a 70-year-old child leads the country.

As we saw throughout the campaign, all Trump cares about is winning and being admired. If you praise him, you can't be such a bad guy (see Putin, Vladimir). If you criticize him or threaten his view that he is the Best Person in the World, you are a loser. (A so-called loser???) Even though Trump is now POTUS, he just can't get over the fact that Hillary Clinton won the popular vote. Instead, he has become obsessed with it; going so far as to repeatedly spread the lie that millions of illegal voters went to the polls for Clinton and launching a voter fraud investigation with absolutely no evidence to back it up. You won the big prize, guy! You’re the president. Maybe let this go and focus on leading the nation?

This election mania spilled over into an unhealthy fixation with his inauguration crowd size. As anyone with eyes (and various crowd analysis experts) could tell you, Trump's inauguration had far fewer attendees than either of Barack Obama's, but Trump just couldn't accept that. If he hadn't made such a big deal about it, the news would have passed quickly, but because he's so self-obsessed, we talked about it for days. He not only sent out his press secretary to lie for him, he went so far as to call the National Parks chief to request additional photos. He couldn’t help himself.

Trump's pettiness truly knows no bounds. Last week, he also lashed out about the ratings for Celebrity Apprentice during the National Prayer Breakfast, slamming current host Arnold Schwarzenegger and asking people to pray for his television show. He also made a talk about Black History Month about how the media has wronged him. Poor presidential baby!

To put it in Trump-speak: This is not very precedential! Sad!

And that's all before we even get to his unhealthy relationship with Twitter — you would think that, as president of the United States, he would want to project confidence and control to his constituents, to address real issues affecting our country and the world. Instead, he has continued to use it to attack those he thinks are being mean him. (Being mean to him = not agreeing with him and saying that.) Instead of using his enormous platform to talk about the shooting in a Quebec City mosque that killed six or the fact that Jewish preschools were recently threatened, he yells at his millions of Twitter followers about how Meryl Streep is overrated because she said some stuff he didn't like. Instead of listening to those who object to his policies, he calls them names as we saw when he labeled the Senate minority leader "Fake Tears Chuck Schumer." Instead of engaging with some of the valid issues of the Women's March, he instead chose to mock the event and indicate that because he'd won the election, the opinions of the millions who marched didn't matter. (He conveniently forgot that he lost the popular vote by 3 million.)

Sir, you are the leader of the United States, not an announcer agitating the crowd at Wrestlemania. The opinions of the American people should matter to you. You know what should definitely not matter? Whether people think you own a bathrobe. (Pretty sure you do, but it doesn't matter.)

Sometimes it feels like Trump's childlike antics are just a distraction from bigger issues — like the fact that he's delivering on his campaign promises in horrifying ways, like signing an executive order that essentially guarantees that more women will die from unsafe abortions and banning non-U.S. citizens from seven Muslim-majority counties from entering the country. But to call his behavior just a distraction is simplistic — Trump's outbursts do more than steer the conversation away from the unpopular policies he's implementing left and right; they show us his priorities. Or rather, his priority, singular: Donald J. Trump. That’s a problem, because as the president, he’s supposed to care about his country above all else, and not his fragile ego and massive insecurities.

With his presidency, Trump dove into the deep end head-first before figuring out if he can swim. And now we’re all drowning with him. Sir, you are the PRESIDENT OF THE UNITED STATES. I’m begging you, grow the fuck up. (And also, maybe remove the actual Nazis from your inner circle.)
