@Fink Racism answer. I'm going to tread very carefully here because I don't want to publicly bash my own community too much.
Jews are not perfect. There are always 'bad apples' in every community. Sadly, sometimes there are also social trends or attitudes in parts of the Jewish community which are accepted or not called out as much as they should be. This means that we do not always live up to the standards of our own religion - that all humans are created 'b'tzelem Elokim' (in G-d's image).
There is also a diverse range of Jews in the community. Most UK Jews are Ashkenazi (although that doesn't equal white-skinned - many can look Mediterranean or Middle Eastern). Some are Sephardi, Mizrachi (from Iraq/Iran and further East) or Yemen and therefore have darker skin. To a non-Jew, I look mostly South Asian - to a Jew, I would pass for Mizrachi or Yemenite. The groups who would stand out the most within the UK community as 'different' or 'other' are Black or East Asian Jews.
I have not personally experienced much racism within the Orthodox Jewish community. Many Jews are sensitive to prejudice, and will call out this out in others when they recognise what is going on. However, a couple of years back the Board of Deputies did a report on racism in the Jewish community (full disclosure - I took part, with some reservations). The report is here.

The major caveat is that this covered the entire Jewish community from Reform to Ultra-Orthodox. I'd say most of the participants were from the Reform to Modern/Centrist Orthodox end of the spectrum - very few would have been coming from within the Ultra-Orthodox community. But there were definitely issues around language and lack of respect flagged within some (I stress, some) sectors of the Orthodox community. From my POV, this is not good or something I am proud of. It is something we need to work on as a community.
And yes, as per one of the DA threads I totally acknowledge that this is a two-way street and that there are also very real issues with violent antisemitism from parts of the non-Jewish Black and Muslim communities (which can affect the Jewish response). I've heard several Black Jews comment that they are stuck in a hard place between these two communities, as they get stick from both sides. It doesn't affect me directly because I don't identify as Black and can 'pass' as a Mizrachi Jew. But I hear the problems.
Israel is a different story. Yes, there likely is some racism towards Ethiopians there - but the context and the background is very different to anti-black racism in the US and must not be viewed through that lens. There are also very real issues around a) integrating the Ethiopian community because the first generation were completely unexposed to a Western lifestyle until they arrived in Israel, and b) the halachic status of the Ethiopians as Jews, because geographically they 'split off' the mainstream Jewish people before Rabbinic Judaism (which is essentially what all Orthodox Jews follow today) fully developed. There also debates even within the Ethiopian Jewish community over whether some of the later immigrants to Israel were really Jewish or had assimilated out.
It's not an easy conversation to have. But I hope it helps to hear this.
