No. Having the freedom to say something does not mean that you have a right to have any platform you want.

Private platforms owned by individuals or groups are allowed to deny a platform to anyone they choose by right of the platform being their private property.

Public platforms are a different matter. Because individuals have the right to free speech in the public arena as members of the public, it is unlawful to deny them access to a public platform. Similarly, we all pay for public property. Those in power or the majority should not be able to remove from the minority the liberty to use public facilities.
