The term "terrorist" doesn't have a single fixed meaning. It's context-dependent. Pretending it's not context-dependent willfully misinterprets the speaker.

A lot of words function like this. E.g., "believer".

When a christian asks me if I'm a believer I might say yes.

But then I'd probably say no if a wiccan asked me the same question.

Obviously, that doesn't mean that everyone (or no one) is a believer once you fix some additional context.

So in summary, according to the sense in which the USFG is using the term, you're simply not a terrorist.

Everything else about your post is just a slippery slope argument, which may or may not be valid, but certainly isn't well-substantiated.
