That's a strong point. I have always thought of freedoms being limited by the effect they have on others' freedoms. You can't use your freedoms at the expense of someone else's freedom. E.g. you can't kill someone because you are restricting their right to live. That being said, speech is kinda nuanced. Because, spoken word does not directly affect other freedoms. In extreme cases, like shouting "fire" in the theater or "bomb" in an airport, speech is limited because of the direct link between it and the result. But that's not really the case with propaganda, even if it is the goal to misled. To conclude, we are victims to our own freedom of speech if it can be used against us. If someone can say outrageous things and there are people that hear it and don't immediately think "huh, that's crazy" and walk away that is a different problem. But I don't think the solution is telling him to go sit in the corner, I feel like this wrong and also polarizing.
