They have freedom of speech and the right to disagree.
I do distinguish between loyalty to the country and the government.
Our government was founded by the constitution but our country was founded by the Declaration of Independence.
In my mind the Declaration gives us the right and duty to replace an oppressive government. This gives it precedence even over the Constitution. It is a very radical document and really makes the United States the most revolutionary country on earth.
The second amendment simply states that the people ( not the government or one of its entities) has the right to keep and bear arms. This backs up the Declaration .
I do not think talk makes them traitors it takes some serious actions.
The left conveniently forgets that these same rights would also be used to keep an oppressive far right government in check.
