See… the thing of it is… the Government cannot suppress your rights. If your boss says get up and salute the flag when the anthem is played or find another job, and it IS in your contract, it depends on how wishy-washy your boss is. If a public information transfer provider refuses to transmit your information as offensive, that is THEIR right as a privately owned, and not governmentally controlled, entity.
These things are left to individual choice. And if you are posting “gas the Jews” memes, then you should understand better than anybody that not all individuals make the same choices.
