The first amendment protects US citizens right to speak freely in public and private venues from being retaliated against by the government.
It specifically means you cannot be denied government services, support our rights because of any opinions you express publicly or privately.
It does not and never has obligated any private persons or business to listen, rebroadcast, or not *react" to what you say. You have never been protected from the consequences of your speech within your community, nor has anyone been required to enable it. It has never been a protection against the speech of anyone else, for example rallying their community to speak against you or for other private services to deny you patronage.
