As people here know I'm European. Even though Switzerland is not in the EU (thankfully), and my nationality is Swiss, I define myself as an European. Why ? Because Europe is SMALL. And yes, dear Americans, I'm NOT a "Caucasian", because that mountain range is very far east where Asia meets Europe. To me, Europe is not a continent, it is a part of the Eurasian land mass, and only some old arrogant colonists had the nerve to define it as a continent.
Now what do I like about Europe ? Well, first of all, nowhere else on earth you will find so many really different cultures and languages on such a small amount of space. You can go to Africa, and from Ghana over to Kenya down to Zimbabwe you will find different languages too, but in regard of culture you find a lot more similarities than you will find when comparing a Finn to a Portuguese.
The same happens when you go from Mexico through Central America down to South America. Of course there are different cultures and customs, but colonization has wiped out a lot of them, as in Africa too. Asia is different. But Asia is BIG. That's the difference. When you go from Thailand through Malaysia over to Kalimantan and then cross to Indonesia, you will notice the differences of course, but there are still more similarities in culture than between an Islander and a Greek.
And the best thing about Europe is that after centuries of war, we have learned (learnt.....;-) to get along with each other despite all those differences. That's not obvious. Because we're so small all of us have neighboring countries which speak a different language, and we're almost forced to be multilingual as a result. You will hardly find a German, an Austrian or a Scandinavian who doesn't at least speak some English. Same as here in Switzerland, where most of us also speak some basic French or Italian.
Well, maybe the bigger nations like the Brits, the French or the Spaniards don't feel the need for that because...erm...they used to be the powerful colonizers, so "the OTHERS please learn OUR language" ;-)
Anyway, even though Europe today is only a shadow of what it was before, gone have the guts and the independence, there's still the diversity around where you can choose between Spaghetti all'olio and Filet Mignon, a Wienerschnitzel and a Paella, you can climb up mountains or go to the beach, and you will find the most gorgeous ladies the further South you go ;-)
And you don't necessarily have to talk politics, because there's too many political parties to choose from, and yes, they really have different views to offer....
Of course there are lots of negative points in Europe too - as there are everywhere. But after all I couldn't have been luckier than to be born here. We have the advantage to be on the pulse of where it happens. Nothing is really far away from us, except America and Australia. And so know sooner than others what happens and why. We live with history (we have an old one), and hopefully we're able in future too to draw the right conclusions of it.
You might say why leave Europe when it's such a good place ? Well. that's a decision which is purely personal and has more to do with people than with anything else....;-)
