Your answer was great, and no need to go further. But just to clarify what I meant...
Direct exposure would be first hand. Living in the country would count, but direct relationships with people from those countries count too.
I'd rate RL relationships as 'direct', and not online ones, more just because of the amount of filtering present.
Indirect is more Western music, movies, forums like this, etc, or local sources discussing the US, UK, etc.
So you pretty much guessed my intent anyway.
I have closely known multiple people from Western countries in person, yeah. I would say that a lot of online relationships do count, though, based on my experience of knowing people online and then later extending our friendship offline. I have noticed little difference between their online personality/presentation and its offline counterpart in most cases, both with other Arabs and with people from elsewhere. It usually feels like we've both known each other for a while when we meet in person for the first time.
Then again, maybe I've just been lucky.
