I agree with the quote.

But on the flip side also imagine if I go up to someone and say like "You asshat, you're so bad and dumb and no one likes you" and stuff over and over, right in their face. Then say they go inside and shut the door in my face so they can't hear me anymore. Have I been deprived of my liberty by being kept from telling someone else what they don't want to hear? I don't think so.

I think the value of the message is important (facts vs personal attacks) in this equation. And also the ability to say something doesn't mean the ability to say it to one particular person, nor does it demand they listen. Perhaps public figures like representatives are exemptions, as they should be required to listen to their constituents. But most people are not required to listen to everything that is put in front of them, nor should they be.

However people should have the ability to broadcast ideas broadly. However people shouldn't be able to shout fire in a crowded theater. The line between the two is very fuzzy and complex when you try to find exactly where it is.
