You have no understanding of the first amendment. It applies, of course, only to the
government's response to speech.
I would be curious to know what you think free speech means, if it doesn't mean speech without consequence.
You can say anything you want, and the government won't intervene. That's all free speech means. Other people, groups, and corporations are free to judge you, criticize you, exclude you from their platforms and private events, organize boycotts against you, criticize people who agree with you, criticize people who choose not to exclude you, and so forth. You may dislike that they do those things, but they are free to do so without government interference, because of free speech.
You, in turn, are free to criticize and exclude them in a similar manner. This is dialogue, and a desire to promulgate your opinions but have others not promulgate their opinions (including when they're about you) is the height of hypocrisy.
