>The US government has no right searching through it.
Well they just made it a right. What are rights? Rights are not a natural construct, they're whatever the government decides. So if the government decides one thing,. tomorrow it can decide another thing.
It's not a US issue, every country you will go to can change their rights willy billy based on the current boogie man: terrorists, COVID, Russia, Iran, right wing "extremists" etc
In the UK or Germany you can be fined, swatted or arrested for tweets and wrong think. Why? Because government made that a right.
I'm guessing you're a US citizen, because this isn't about the US. Many countries in the world are more or less puppies of the US government, it's not like we're living in an isolated world where the decisions of the US government don't apply to others because they're not US citizens. This is showing a general trend, which doesn't concern just visa applications.
I'm not and I never said it is, I was just saying it's a bit hypocritical for people to complain about governments wanting to see your social media before letting you in the country, while being OK with giving up your biometrics.
You might say you're also not OK with giving up your biometrics, and then I would say, well why are you going to places that do things you're not OK with? Just stay home or go to other places. Why complain about the politics of countries you're not a citizen of and can't vote? Their country, their rules, only their citizen can enact change.
And BTW, I'm OK with governments wanting to see your social media before letting you in. Where I live in EU, there's a lot of middle eastern "refugees" whose social media is full of support of terrorist orgs and calling for death to Israel. Why would you want to let such people in? Would you want those people living next to you? If they're that brazen and stupid to be so open about extremist beliefs on social media, they don't belong in our society and shouldn't have been let in the first place. Granted that won't stop all these extremists, but it will at least stop the really dumb ones.
I expect my elected government to prioritize the safety of its taxpayers over the privacy rights of foreigners and visitors.
Your freedom of speech ends when you're physically and practically disturbing other people's freedoms. Weird how people don't get that.
Inspecting visitor's social media doesn't break the constitution same as how inspecting their/your luggage at the airport doesn't. Border checks are a thing orthogonal to the constitution.
Employers will also Google you and judge you based on what you said on social media. If your profile is full of swastikas or other schizo shit, you probably won't see an offer. Why shouldn't countries do it? Do you want dangerous people let?
So no, that doesn't break the constitution.
I'm afraid we're going into a weird timeline where authoritarian figures in power(not just government) are having immense amounts of data for people, and the technology to go through it without much effort. It's a good time(if it's not to late) for everyone who cares about their privacy to start getting as much as possible outside mainstream social media and centralized accounts(google etc)
