Comment: I didn't write the Constitution.

The question is whether speaking against the Constitution is treason. The document itself defines treason. It says treason is waging war on the states or giving aid and comfort to those that are waging war on them. It says, as far as the Constitution is concerned, that is treason and only that.
As for abrogating rights, it may be a crime, but it isn't treason. Not all crime is treason. I might steal your lunch money. That would be petty theft, but it isn't treason.
Speaking out against the Constitution isn't even a crime, much less treason. Breaking an oath? Is that a crime? I know adultery is breaking a marriage vow. It may be grounds for divorce, but it isn't a crime. It isn't treason.
