Hi again.
I lived in Ireland for 3 years during the troubles and worked there for a further 25 years (working for a US multi, based in the UK); I guess I know it very well.
Racism is a fact of life in Ireland, you only have to Google it to see for yourself what the numbers are; it would be foolish to believe otherwise. That said, there is racism everywhere (not only Americans); my own opinion is that Xenophobia is probably a better word to describe it, where people are envious of well-educated foreigners coming to their country and getting the best jobs, particularly in multi-nationals; by definition, this is not racism, people just don't like foreigners taking their jobs, they don't care what colour or planet you come from.
Ireland on a whole is very friendly, but at the same time very conservative. Religion (particularly the Catholic faith) plays a significant part in all aspects of life; 80% of the population identifies as active Catholics, the next biggest group being no-belief at all, so as far as religion goes, with other groups making up barely 1% each of the rest; that said, Ireland is very tolerant of other religions and the State makes no attempt to interfere. If religion plays a part in your life, you'll be left to get on with it. Inter-racial relationships are unusual, should you enter one, you can expect some kick-back. If you're not religious, you really need to understand what that means to people who are, you will be in even more of a minority than you thought.
If I had to describe life in Ireland; Dublin is a city, many people of all shapes and sizes live and work there. It is expensive, the traffic horrendous - when I first went there it had no interstate highways to speak of. Housing is in short supply and because of that, also very expensive. Anywhere else in Ireland is more rural, there are other towns, but they are nothing like Dublin. Private healthcare is very good, state-provided healthcare is, in my opinion, indifferent; it comes down to costs; many Irish people become Brits and pop over the border and register with the UK NHS from a family/friends address. As a place to live, Ireland is 14% more expensive than the rest of the British Isles; the Numbeo website will give you lots of information, including Cost Of Living, Property Prices, Crime, Health Care, Pollution, Traffic, Quality Of Life and Travel; this link will take you there.
The other issue I would mention is sectarian violence; it's nowhere near as bad as it was, but it's still there, predominantly in the North where they haven't gone away and it occasionally rears its ugly head; it's quite easy to unwittingly do something silly. My advice is just to be careful as you travel around and if you have any political views, keep them to yourself.
To try and answer your questions:
As a African American living in Ireland would I be embraced as a positive ..... No
How are Americans living in Ireland regarded ..... as not being Irish, so negatively.
Are people of color in Ireland seen so seldom ..... yes.
Do people of color in Ireland experience a great amount of overt or covert racism ..... explained above.
How is interracial dating viewed in Ireland ..... not good.
Hope this helps.
