Perfection is the enemy of the good. We can't have perfection. We can't fix the people themselves, which is what it would take to do this non-violently. Without some ideological authoritarianism for this issue.

You see, your definition of 'free speech' is a violation against others. It is outcome based, not opportunity based. You want an outcome that any speech, even the most disgusting, MUST be hosted and broadcast by others and may not be moderated for any reason, even performance, resisting DDoS/spam.

Forcing others to carry your speech is a violation of the liberties of the relay/host and your liberties end when others begin. Adapt. Go door to door to get to the grandmas. Do the work to get them into your relay. You have the means. You have the opportunity.
