I think you're missing the basic distinction between private parties and government.

Private parties (including companies) largely have freedom of association. There are (theoretically) protections in "commerce" against a company discriminating against a person or group based on "innate" factors (such as skin color or gender).

But largely, people and companies have a wide degree of latitude about what they are and are not allowed to do.

The government, on the other hand, (theoretically) is largely not allowed to stop people from saying things or associating with each other, and when these prohibitions are in effect they're subject to both documentation and review. This is "theory" because the government has done lots of shady things.

The government, similarly (and theoretically), is bound by a variety of procedural constraints, such as due process, right to see an attorney, right of the attorney to request your presence, right to a trial, etc.

There's a categorical distinction between:

I, a private party, am offended that I face consequences of offending someone else when I would prefer not to face any consequences.

and

I, a private party, am abducted by the organization in this country with a monopoly on violence and which interprets all laws, and I vanish with no recourse from anyone.

I mostly agree with you.

> Those both seem pretty obvious, but put the two of them together and it means people can lose their jobs or not be hired for stuff they tweet. How do you resolve that?

If the employer happened to see it, then yes I think that's well within rights. But I think having some random stranger see something and actively campaign against the employee to their employer is a little bit different. It's not illegal, nor should it be, but there are plenty of things that are legal but still not good behavior. I would consider this under that umbrella.

Why should we make an exception based on religion but not on political viewpoint? That is logically inconsistent. There's nothing special about religion.

"Getting in trouble" at work and being disappeared are so freaking different that there is no discussing it. If you cannot see a difference, you are blind.

What sorts of trouble and benign speech are you talking about?

Are these people in your realm being picked up off the street by the police, drugged, put into an airplane, and then being dropped into the ocean over international waters?

Or are these people having the things they've said repeated widely, perhaps out of context, to other people, who then decide "sheesh, maybe I don't want to hang out with / work with this dude." ?
