Sigh... Such a predictable response I should have address this in my original comment
Sure the Right of association, and I suppose property rights give them the legal ability to this.
However most of these platform publicly and loudly proclaim themselves as "Free Speech Platform", open to all points of view, open to all. Even in the public responses to the outcry over the bannings on Patreon their first statement was "See support free speech but...."
Once they add the but, they show themselves to not be supporters of free speech, instead they show themselves to be supporters of limited speech as defined by theit terms of that is acceptable speech.
Saying "We Support limited acceptable speech" however does not make for a good sound bite.
Claiming to support free speech while imposing speech codes, rules and terms is Fraud IMO.
So if platforms want to censor, want to limit speech fine, they need to stop claiming they support free speech when they do not. To do otherwise should be considered fraud
Most of these platform get to be very very large to the point of more or less monopolistic due to their claims of supporting free speech, then once they are the market dominate force they bait and switch their users and become a limited speech platform. That is a classic old as time form of fraud.
>>I think the scarier prospect is people thinking that property holders should be forced to act as law enforcement within their domains, and to make determinations about civil rights.
I am not even sure what that means or the point you are attempting to convey here, Nothing I stated indicated that property holders should be forced to act as law enforcement.....
>>Free speech simply says that you can't be arrested for speaking.
No, that is not what "free speech simply says" Free Speech is a ethical axiom. Even wikipedia does not have such a limited view of the concept, the first line in the Wikipedia entry on Freedom of Speech is "Freedom of speech is the right to articulate one's opinions and ideas without fear of government retaliation or censorship, or societal sanction" See the "or societal sanction" part.
