not helping what? he's making a perfectly valid point.
Not helping, as in not helping with the arrogant/ self important stereotypes, and no he does not make a valid point. Don't be daft.
Anyway, let us back track a little because you seem to be a bit confused.
Common US stereotype: American's are terrible at geography (i.e. can't find France on the map). PFISAB says, so what's the big deal I bet you can't name the states that surround Colorado. In America's short 235 year history Utah, Wyoming, Nebraska, Kansas, Oklahoma, New Mexico, and Arizona have enough importance on the world stage to be easily identified on a map much in the same way one should be able to identify France on a map? I don't think so. Collectively they don't have enough importance to be identified on a US map an American citizen. Really Americans should be able to do so, I'm just saying I wouldn't fault them if they couldn't.
This of course is absurd, so I made my analogy with England's West Midlands, and then PFISAB counters with "I'm just saying (...Texas is pretty big)". Now ignoring the fact he now talking about an entirely different state, and that yes Texas is probably one of the most easily identifiable states, he is essentially saying it is big therefore important. Texas is a single state in a union, and although significant to US and North American history, it did not play a role in shaping the world we live in today as again let's say France.
So what does this have to do with what you wrote? I actually agree with some of what you wrote. I also don't particularly care about American's perceived lack of geographic skills, because I've seen first hand much worse here in Japan. This, much like a lot of the stereotypes written here, are NOT unique to Americans. I feel we get a pretty bum rap. However when someone writes shit like PFISAB did, they are perpetuating these negative stereotypes. So my point, which is "shut the fuck up, you're not helping", stands.
And since you asked, just off the top of my head: Brunei is located on the island Borneo, shares a border with Malaysia (and Indonesia?), is a Sultanate, and predominantly Muslim. That's all I know and could actually be completely wrong as I quite often mix up countries that start with a "B".
