We did have a way. It was called a kill file. Unfortunately, we don't have adults anymore. We have children that need to be protected from hearing anything they don't like to hear and must be giving the right to shutdown people's speech they disagree with ("heckler's veto").
If necessary I'll use a public club i.e. the government. Everyone will rightfully shout "Free Speech!" Maybe I don't use the government though and just get the speakers platform to walk away by asking platform to do that, or yelling at them.
And the I'll sleep easy with the knowledge that no one will hear those lies. No one will think those lies.
