Saskia, I don't really see where this is going. There seem to be a lot of logical disconnects - Your friend with cancer seems to have encountered an arsehole civil servant (we have them too BTW), I don't see what that has to do with racism. Ditto, the local police being worthless and not doing their jobs (that happens here too, it seems the police everywhere seem to find it difficult to find the wit to deal appropriately with sexual crimes).
I'm with Martin Luther King Jr. we ought to judge folks by the content of their character, not the colour of their skin, or the god they worship, or what school or university they went to, etc. etc. The current UK Prime Minister is white, went to a 'good' school (Eton), a 'good' university (Oxford), and look what a worthless idiot he is. A prejudgement on his easily perceived superficial characteristics would be proved wrong.
The only trouble the large Pakistani-origined Muslim family across the street ever causes is their kids playing football in the road. Just an ordinary family in other words even though all the males go out dressed in pyjamas of a Friday lunchtime. The two 2 1/2 Odinists who live in the road are quiet and keep themselves to themselves, and I suspect nobody but me and SWMBO knows what they are. The Black families next door and opposite (British natives and Francophone immigrants respectively) are no trouble, they're just ordinary families. The Ukranian lesbians downstairs and the English lesbians next door are fine too. The mad cat lady who lives at the other end of the street is what she seems, but she's normal otherwise. I can find no major faults in the actual content of the characters of my neighbours, but someone somewhere is ready to pre-judge those people because of one of the perceived characteristics I've mentioned and they would be wrong, both in judgement and morally, to do so.
The only truly suspect character in my entire street is this old beardie-weirdie with long grey hair who lives at one end and drives around in a red convertible sports car (At his age? Really?) with some blond floozie who's even older than him. Well sketchy if you ask me. You see him carting weird electrical equipment into the house, and bottles of chemicals. Trust me, we're gonna see police tape around his house one day, one of those tents over the door and lots of CSIs walking in and out in bunny suits.
