What if a stated opinion is seditious? Is not a political ideology advocating Revolution and changing form of government against the law anymore? Or is the blood price only paid when the Lavoy Finicum’s of America rail against the incremental creep of big government?
No, not unless you act on it or actively plan to do so. It never has been. The communist party has never been outlawed. Beliefs and opinions, however wrong, are not crimes. Thank God. Remember the hysteria about "anti-government militias"? The left would love to have such laws on the books to use against their opponents.
