Fair enough.
My original parent comment asked where you can speak freely online, which for the purposes of my argument I'm equating to US law regarding free speech. (This may not be the angle you're coming from.)
Most hosts will allow you to publish things that fit that description. To take the examples given in this thread: if you want to publish an image of the Confederate flag, or publish something and not have Twitter or Facebook placing ropes around your content, publishing your own website is going to solve that problem for you.
Now, you're not wrong, there are limits to that, but I'm struggling to find out how those limits apply to this conversation in any realistic way.
