He asked everyone to "name an of Iranian actor".All you "demonstrated" was that you have the ability to google for a list of Iranian actors. You haven't gotten anywhere near disproving my actual point, which is that there are no Iranian/Persian actors as well-known as Jake Gyllenhall. I'm pretty sure you realize my point was not "there are no Iranian actors that anyone in America has even heard of".
All I know is what I can get from the words you choose, and your own exact words were: "Hell, just name an Iranian actor, I bet most people here can't." That was the specific challenge you made, and I responded to it. You have no business crying foul when you were the one who chose to phrase the challenge in that way. If that wasn't the idea you intended to convey, then the mistake is yours for choosing such an ill-conceived, hyperbolic way to make your point. Take responsibility for your own choice of words.
And yes, I made the list with help from Wikipedia, but just about all those names I listed were actors I was already familiar with and that are reasonably well-known to the public at large, even if not everyone knows they're Iranian. You said you bet that most people here couldn't name an Iranian actor. I'm sure most people here do know the names Adrian Pasdar, Catherine Bell, and Shaun Toub at the very least, and though I'm not familiar with Sarah Shahi, she seems to be pretty popular with others on this board, and gets more Google hits than Pasdar and Toub put together.
Okay, so maybe I've just shot down a single point you made rather than addressing your core argument. But an argument is only as good as its evidence, and the specific claims you're using to support your case are highly flawed.
He didn't say "look up a name of an Iranian actor".
If you had to look up names(which is cheating and we could all do that to answer the question), then you couldn't name one off the top of your head. That is why he asked in the first place. His implication was clear from his phrasing.
