I actually don't think the coup was acceptable, however Zelaya defied the orders of the Supreme Court. The Supreme Court has the final legal rule and interpretation of their Constitution. You are right to disagree with their ruling, but it is binding and proceeding against its edict plain and simple undermines the democratic process. The coup also itself was a violation, but to paint Zelaya as some poor victim of the elite and the Unites States of America is not fair either. He is where he is largely due to his own actions.
