That's what I'm saying. They've defined terrorism to be "political violence" and declared it to be unmitigated evil -- it's sleight of hand. Is a riot terrorism now? Is a revolution? Were the US soldiers who killed Nazis in WWII "terrorists"? It's propaganda. They're hypocritically condemning political violence while engaging in it. They're equating violence by foreign radicals against a country's people with violence by a country's people against its own corrupt government.
It's putting George Washington, Malcolm X and Osama bin Laden into the same category for the purposes of collective condemnation. The only way it makes for a useful method of categorization is if you're already in power and want to disenfranchise anyone without the political power within the existing system to make change, regardless of the legitimacy of their position.
It is terrorism. By definition: the use of violence and/or intimidation for political goals.
Perhaps you could argue that terrorism is a constitutional right?
