Cool and Good aren't the same thing.
Some of the best people I've ever met were pretty low key and definitelly weren't overly concerned with presenting an appealing image to others.
What's percieved as coolness usually is just dressing the part and acting the part and in my experience "cool people" are often people who just take the whole maintaining a public persona thing to quite extreme levels, pretty much playing a role as if life was a Theatre play.
Since I'm an European, lived as an immigrant in the UK for over a decade and was a regular reader of The Guardian for most of that time and even for some time afterwards, your ad hominem missed the target by a huge distance.
Your post says a lot more about you given that you've jumped to such a conclusion about me from what you read and chose an ad hominem as "counter-argument" than it says about me.
