I understand that, but that's not really my point. Yes, they have an isolationist and xenophobic bent. But while it's understandable that having a social media presence full of sketchy / terrorist / trafficking / whatever might now be a reason for a country to deny a visa, it creates the question of what they do with innocent people who simply refuse to participate. My question is what happens if you don't have any social media or smartphone at all? Will we be completely excluded from being allowed to travel freely unless we post our thoughts on a daily basis?

Yes, because even if you do, they will find other ways to exclude you. Their stated goal is to exclude as many non-Americans from the USA as possible, regardless of whether they consider you "innocent" or not.

I mean, that is a US problem - or the problem of any country which chooses to destroy its own tourism sector. And searching social media is ancillary to that, as you say, if the main goal is simply to exclude people.

I'm talking about (per the article) whether self-exclusion from social media will soon become a worldwide red flag for travel.

Oh my bad, since you mentioned American tourist visas I assumed you were only talking about America. I have not been following similar laws in other countries, maybe their motivations are different than the American intentions of completely shutting off immigrants from the USA.

That's very typically American. Being so focused on America without understanding that the choices of the American government have huge consequences for the rest of the world. You keep saying that this is all about the Trump regime keeping foreigners out of America. And that is true. But that is not the big picture. As an American you should be more worried about whether you will be allowed to leave your country, or go anywhere else when or if you want to, once America sets this precedent.
