That’s the point.
You, as a common citizen, should not have to. But the moment you feel like to share your thought or opinion, you should be identifiable and made responsible for it.
The current social media outlets shield behind the argument they act solely as channels while at the same time fostering and allowing for “anonymous” groups or individuals to spout whatever views they want, often views that deter from advancing social and civilizational progress. Hence the current state of the world, with authoritarianism on a rise and hight like there wasn’t in nearly 70 years.
When the internet was made of individual websites, the person behind it was automatically made responsible for whatever they put on it. That was fair and reasonable.
Pushes like this, is assigning suspition/guilt before any wrong doing.
I will grant the overall facilitated acess to pornography is damaging the kids. There are already enough studies showing how the early access to porn is related to bad interpersonal relations on social, emotional and sexual level.
But this does not imply you should be identifying yourself to access adult content or anything on the web. Just impose curation. If it’s available to the public, you’re responsible for it.
Old school “dirty” books and magazines stores had controlled access and the really hardcore stuff was well out of reach of who should not get to it. Free porn is nice but there are things available that should be behind pay walls or at least registry, with identity verification.

No, it’s not my point, although there is a difference between expressing ideas, no matter how contrarian or controversial they may be, and spouting hate or other positions detrimental to advancement.
I am aware of what you mention of companies sniffing for the social media of employees and potential applicants. It is a shameful practice. And if it is illegal in my country, has it is viewed as trespassing on one’s privacy, it should be as welll any and everywhere.
Nobody should be ashamed nor afraid of expressing their opinions and ideas. Unfortunately, freedom of expression is often confused with the hability of saying whatever one feels like it, which is not.
What you describe (and fear, I take) is persecution. And that already tells whatever system an individual lives in is already deep into veering towards blatant suppression of rights. The US case is so off the rails it deserves an entire category to itself but it is only one among too many.
On the question of banning access to pornography I am completely against it. Yet I can not and will not deny the amount of evidence that supports that early and easy access to it is in fact tainting how people in general and kids in particular understand how relations are constructed. Pornography is really good at teaching wrong things. Nothing against it per se, it can be fun, but it should be consumed just like sugar, tobbacco and alcohol: in moderation and knowing of its ill effects.
I personally started reading erotic books much sooner than it was supposed. I recognize that curiosity towards sex and sexuality is ingrained in what makes us humans. I’m not advocating for banning adult material of any sort. What I would like to see would be clear boundaries for that specific content, for it not reaching those who are not expected to access it unware. It can’t be written off to caveat emptor. Even less because a lot of it is “free”.
The web is as it is today in great measure due to porn. There was a lot of money being poured into technology to facilitate access to it and in high definition. Let’s be thankful for it but that is it. It can be almost ubiquious nowadays, along with casinos and crypto. It’s too much and too much of a good thing is bad for everyone. Remember death by snu-snu.
I have no illusion we, as a species and a civilization, are going through a very dark period. Again. All the prior should have been able to sink in the lesson but we are either too sttuborn or too stupid to learn. Censoring, wide spread control of ideas, knowledge and thought is detrimental to a fair and free society.
Excuses like “protecting children”, “fighting terrorism”, etc, are, as you correctly said, excuses to make advances on individual rights and liberties. But we should be as concerned by now that companies do whatever they can to reach their goals and we are being force fed too many things that are not good for us. Two wrongs don’t make a right but something has to change. Perhaps ceasing to be afraid of being responsible by one’s own ideas and words would be a good start. Maybe stop feeding social media would be another. And perhaps reigning in companies on bad practices could be another.
