The term terrorist

One man's terrorist is another man's freedom fighter

I think that terrorism is misplaced anger.

Shouldn't these sorts of threads be on the politics board?

Well, anyway I think the word is probably the most-abused word in the history of language, or close to it. It's completely subjective, dependent on the political biases of the person or government using the word. For instance, al-Qaeda are called "terrorists" when they're in Iraq, but when they're in Syria they're called "moderate rebels". Whereas other organizations in Syria with the same ideology, such as Daesh, are called "terrorists". The German Nazis called the French resistance "terrorists", and later the same French who had fought for the resistance called the Algerian national liberation movement "terrorists". The US calls Daesh and Hezbollah both terrorists, though Daesh and Hezbollah have completely different ideologies and methodologies and are at war with each other as we speak, and they call each other terrorists. Whether you call someone "terrorist" seems to depend more on whether you agree with their political goals than on their actual ideology or tactics. The word is close to meaningless. It basically means "a political movement I dislike".
