Conversation

Remember that whenever people scream about "mah freezepeach" as reason to be allowed ti behave any way they like:
The "Right to Free Speech" refers to a (supposed) protection against S̲t̲a̲t̲e̲s̲ and possibly their sub-organizations to infringe on some forms of expression,
but it does NOT grant you any right to speak anything at any person that does not want you to.
They don't have to hear you or even give you a platform, because they are not the State, with (maybe, depending on location) that obligation.

For free speech to work, it by nature also includes its inverse, the right to not be spoken to.
