By your logic, every non-European in Europe is an invader. I agree.
Eh? The Europeans are the ones who did all the invading, dude. Ever wonder why most Americans are white? It's because Europe invaded North America. You're welcome.
Also, a bit of research into Europe might reveal to you exactly why black folk (or folk of African origin) exist in Europe. They didn't evolve in the ghetto, you know. There was this little incident in history, called the slave trade.
Thus, now we have established that black people didn't evolve from the European or American ghetto, are you seriously suggesting that all the black folk in the UK, France, Holland and other places all around Europe, are actually 'invaders'?
