I don't know this for a fact, and it's always possible that some black guy who is very unique, intelligent, and charismatic might be an exception, but Hungarians generally don't like black people or even if they have nothing against them, they probably wouldn't date them. The most angry and racist Hungarians are in the Northeastern part of Hungary. I'm just encouraging them to realistically assess countries and to be aware of their surroundings, like any good traveler, for their own safety.
There are also gypsies in Hungary and I'm not sure how they would feel about black guys. Even the ones who look clean often don't seem to wear deodorant, so they have quite a bit of BO. From the years of research, talking to the local men from these countries, and black men that have been successful abroad, these are the countries black men are adored.
From what I was told and observed, its improved tremendously in the last 10 years.
There are more countries to name, but these are the best ones.
western Europeans, are very open or even predisposed to dating Africans.
Some of the Nigerians and Senegalese males you see in places like London or Paris are super charming, attractive, and very well presented.
If you are in a bar in Finland and start calling Finns Eastern Europeans, you might get the shit kicked out of you. Similarly, I should point out that a lot of people from former Eastern Bloc countries don't like being called "Eastern European"--it's definitely the wrong term to use if you're trying to get on their good side.
Those people who live in countries which are geographically in Central Europe would much rather be called "Central European." In America, we don't use this term, but Americans generally don't give a shit about foreign cultures and know nothing about geography and history, so this is no surprise.
