That's open for discussion, if a person has nothing else to do. Certainly a case can be made that destroying property to make a political statement is wrong, and an additional case can be made that destroying property to make a political statement is counterproductive. A separate case can be made for the principle that a person who breaks the law to make a political statement should expect to face legal consequences. All these cases stand or fall independently of the content of the political views stated.
It's pretty sad that you failed to raise the case that standing up to tyranny was a higher principle than any of the offenses you cited.
