The First amendment proscribes government censorship. If you can’t cope with it go over to the DU were you will find the same illiteracy of the US Constitution as you are demonstrating.
You have no right to be heard. You have no right to impose your speech on any private person or entity not wishing to hear it.
Go read the Constitution. Cite the parts that say the government can enforce speech standards on private persons. Try it.
Let us say for the sake of argument that you are correct about this.
Why did the founders oppose government censorship?
