Indeed, if someone can post their more-or-less unfiltered thoughts on a big social media platform like Facebook, Twitter, etc without ever getting banned, that's a great indication that that person is not part of a "vulnerable" faction, at least in the sense of being part of a counterculture.
So - I guess I'll risk giving one example - if you post a gross exagerration of the risks of SARS-CoV-2 with respect to death or serious illness, or recklessly speculate that recovery from infection does not produce immunity, you're allowed to do that as much as you want. But express the opposite opinion (even if you're literally echoing WHO recommendations such as [far too late] lockdowns being too blunt an instrument or that immunity passports shouldn't be a thing), and you'll be quickly suspended or banned with only a vague reference to "community guidelines".
And then of course you have the irony of platforms like Parler and Gab, which arise in large part due to the phenomenon of deplatforming voices of (primarily) a certain side, and then the mainstream will turn around and criticize these platforms for having a lot of "extremists" or supposed "crazy people", despite the fact that by definition such a platform is going to be populated by those who got booted explicitly or implicitly from the mainstream systems. As a further irony, it's commonly said that "nobody is preventing your ability to speak, you're just not allowed to speak on [insert platform]", and then when you go to that other platform that permits largely unrestricted speech, that platform is yanked from AWS and there's tons of news headlines about how they shouldn't be allowed to platform voice X or faction Y, etc.
So...yeah, the dismissive "how dare you declare these people vulnerable" is very naive and myopic IMO. I think we all know more or less what the current zeitgeist is and roughly what happens when you run afoul of it, and it's not pretty.
I hope I made something close to a coherent point there, I was mostly going stream of consciousness mode :)
See eg http://paulgraham.com/say.html, for further hints.
Unlike a protected class, which you cannot choose to be a member of. Being of a political party is not a protected class, nor should it be.
The "most vulnerable people in our society" are the people who are discriminated on things they are, not things they do. Gab users are not the most vulnerable, because they choose to be who they're judged for.
It's viscerally insulting to see that point misunderstood, because it belies a fundamental misunderstanding of large portions of how society functions in practice. Because of what you said, and people who believe what you've said, people suffer. That's hard to confront on HN, because you don't expect it.
That's a really odd take. Throughout history, many of people have been prosecuted for what in retrospect many would agree are correct beliefs (eg: abolitionists, suffragists, believes in evolution, etc.)
Do you not feel sympathy for these people, who according to you could have just avoided all their troubles by changing their beliefs? Do you not understand how incredibly vulnerable AND critically important a minority belief could be?
Veteran, family status and religion are protected classes you can choose to be in.
