Having lived in the UK as an EU immigrant with Indian, Black and Muslim friends I always found it ridiculous how so many Britons genuinelly thought that Britain wasn't at all Racist, even all the while from all I heard it is spectacularly Racist, well beyond other countries in Europe I lived in.
The entire system in Britain, including the Law, is all about suppressing the most visible effects of all the shit going on there (managing appearances is THE top skill and concern of British Upper Class, especially the English), which when it comes to Racism means punishing people for voicing Racism, but in practice not for acting it - as long as the thing is properly swipped under the carpet, it can be treated as non-existent and there is no need to look into or actually fix it (even when brought up like this, it's dealt with a bit of talkie-talkie, some meaningless measures that just hide the statistics or push down on the reporting that made it visible, and that's it)
More so than other countries in Europe, Britain is the kind of place were the garden looks perfect but if you turn any rock the most digusting things turn out to have been under it.
