I’ll give it to you, the US indeed doesn’t like having passenger jets flown into buildings or ied trucks driven under buildings (nobody does you dingbat).
Uh... That's one thing, but for example Nelson Mandela was designated as a terrorist until 2008. It's a meaningless term (or I guess more accurately a meaningless designation) that happens to include some really bad people. I'm pretty sure I don't need to say that someone's terrorist is another's freedom fighter.
