Unfortunately people from African origins as a whole, not necessarily all individuals, do themselves no favours. The parts of cities in Europe, US, etc where they have settled are almost always crime infested violent places where gangs, violence, drugs, knives, etc rule. Unfortunately they don't respect the law, value education or form strong, stable, traditional families - the percentage of single parent families is far higher than amongst the caucasian population. Then there's the 'culture'. Aggressive, tuneless music celebrating guns, flashy bling, tacky sportswear, violence and disrespect to their 'bitches' and 'hoes'. If we examine the continent Africans originate from we can see the same chaotic, destructive nihilistic behaviour with failed states and banana republics ruled by violent despots where over population is destroying the natural environment and the people are completely unable or unwilling to pull themselves out of their situation. And before any liberals blame nasty whitey - for example Haiti has had independence for over 200 years and it is still a fly-blown violent third world hell hole. Or South Africa, given it's independence and bequethed a fantastic infrastructure by the nasty white man - but the country is descending into chaos, bankruptcy, corruption, epidemic levels of rape, robbery and murder. The SA Rand is on the floor and the last whites with the means to escape abroad are doing so. Then there's Zimbabwe................................. I could go on.
Do you see the pattern? Do you understand why a central European countries without a history of mass African, or even Asian, immigration would be mad to inflict all or some of the above on it's settled, indigenous population? It would be classed as a massive act of self harm, and for what? To showcase dumb liberal guilt, or fill some quota? I accept my views are unfashionable, but the evidence is there to be seen.
