MY VIEW of the dust-up between Twitter and President Donald Trump is simple: The company should treat him exactly like it would treat any other user. But I鈥檒l also admit to a degree of concern about how it treats other users, particularly the company鈥檚 growing determination to regulate opinions expressed on its site.

Twitter, long criticized by the left for its refusal to flag or even delete presidential tweets for which a less-known user might be suspended, finally decided to add warnings to a pair of Trump posts fulminating about the possibility of fraud when ballots go by mail. Given the president鈥檚 history of tweets that are grossly offensive, actually false or both 鈥 like last week鈥檚 despicable attacks on Joe Scarborough of MSNBC, which I won鈥檛 dignify by repeating or linking to 鈥 mail-in balloting is an odd place to draw the line. But the line鈥檚 been drawn, and the president鈥檚 response is a childish tantrum, threatening to shut Twitter down.

Twitter is a private company and it gets to set its own rules. If you break them, the company can alter the terms on which it will serve you. Yes, there are arguments for treating the president differently. For one thing, there鈥檚 a case to be made for the respect due the office, whatever one鈥檚 opinion of the occupant at a given moment. For another, Trump鈥檚 every tweet receives such a level of media scrutiny that flagging what Twitter considers untruths will be redundant. And given the belief by many of the president鈥檚 supporters that the news media distort his every word, social media might be his only means to stay in touch with his base.

Those arguments are not without force, but they鈥檙e not persuasive. I鈥檇 rather that Trump used social media less, and with some semblance of dignity. If he鈥檚 going to use Twitter, however, he doesn鈥檛 get an exemption because of the office he holds.*

But that鈥檚 far from the end of the matter. I worry about the rules Twitter imposes. On the one hand, I admire the company鈥檚 efforts to help users sort between bad information and good on such issues as vaccinations, and I鈥檓 intrigued by the possibility that the platform might imitate Wikipedia in having users themselves moderate content. On the other hand, when it comes to arguments over policy and politics, I鈥檇 rather that no institution, public or private, set itself up as arbiter.

Twitter, for example, has lately adopted a policy of placing labels on 鈥減otentially harmful鈥 tweets about COVID-19, including those that go against the advice of public health officials. But that鈥檚 a dreadful standard. In the first place, public health officials are government employees, meaning criticism of and disagreement with their edicts should be encouraged. Moreover, they can err. I鈥檓 old enough to remember being instructed in no uncertain terms not to buy a face mask.

Twitter relies heavily on expert systems to flag falsehoods, but those systems need, let us say, some further work. For instance, tweets about the silly theory that COVID-19 is spread by 5G cell towers are being slapped with warning labels 鈥 even if the tweets are about how silly the theory is.

Which isn鈥檛 to say that humans will do any better. Trying to figure out who鈥檚 engaging in hyperbole and who鈥檚 lying is a thankless task … and a highly subjective one. Even with the best will in the world, one鈥檚 biases are bound to creep into the work of evaluation.

On the right, Twitter鈥檚 supposed tendency to lean left in applying its own rules about flagging content has become an article of faith. Even should those criticisms turn out to be correct,** Twitter would still be a private company entitled to its biases. True, some think social media platforms have grown so powerful that it鈥檚 time to regulate them as public forums, but that鈥檚 not a view I share. Even if I did, the rules right now are the rules right now, and if the president wants to use the platform, he has to comply.

Still, I find it strange that the company has chosen to draw the line at Trump鈥檚 criticism of voting by mail. On the merits, the debate over mail-in ballots is a perfectly legitimate one. Like a lot of people, I have trouble seeing how we can hold an election this fall if everybody has to wait in line as usual. But I believe in debate. Even when I鈥檓 for something, I鈥檓 eager to understand the arguments of those who disagree. I neither want nor need a parent to warn me not to pay attention.

It鈥檚 hard to make the case for unfettered debate when we have a president who refuses to stop yammering, and whose tongue (and tweets) far too often tend toward comments unguarded, offensive and inaccurate. But a principle isn鈥檛 a principle if you only apply it to the easy cases. And my fear here is the same as always: Once we start down the road of editing error and offensiveness out of the world of argument, not even Orwell knows where we鈥檒l wind up. It won鈥檛 surprise you to learn that I鈥檓 among those who鈥檇 rather not find out.

BLOOMBERG OPINION

* And, not incidentally, the company isn鈥檛 preventing Trump from speaking to his base; at the worst, Twitter can be accused of adding a bit of editorializing when he does.

** Their favorite exhibit is the 2018 statement by Twitter CEO Jack Dorsey that his company was so liberal that 鈥渃onservative-leaning鈥 employees 鈥渄on鈥檛 feel safe to express their opinions at the company.鈥 But he cited this as a problem he hoped to address.
