No, it's not treason because he's not giving aid and comfort to the enemy. They are interpreting his action as a specific catalyst for a call to arms, not an assist, which is indeed dangerous, but it's not what you're claiming.

Why not discuss what is in the article rather than reinterpret and repackage it falsely to fit a sensationalist agenda. This is exactly the type of behavior we're fighting against.
