It's shitty that you feel unwelcome, especially in London, but is there more to this than the cab ride? You don't actually know what he was going to say if you'd said that you were Polish, do you? I mean he might have said "Oh, I went to Poland for the Euros, loved it!" or "My next door neighbour's Polish and makes me tasty Kielbasa" or whatever. It's quite a leap from him asking if you're Polish to you thinking you're being told that you're "part of the problem"
the tone he used when he asked plus the way his tone changed when we told him we were not polish plus the level of xenophobia of what he was listening at the radio at the moment doesn't make me feel that confident about it.
Am I now being targeted like people who get shit thrown at their windows right now?
no
but why exactly should I stay and see how it goes?
why should I stay here hoping that the economy will stay up and the rampaging episodes of racism will go away?
I don't own property in UK, I'm not financially nor emotionally invested in the country at the moment, and I don't see why I should just stay here and hope for the best.
It's not my country and I cannot in any way make a difference: I will just be a passive recipient of whatever British people will decide to do in the next two years.
And even if I do end up becoming a citizen I might still receive the fantastic attention that people who lived here all their lives are now receiving:

You can read everywhere, including in the article recently linked today how people who have been living here for 30 years don't even feel at home anymore.
I didn't build a future in this country yet, but I'm definitely not going to do it knowing that I could end up like those people.
End even if London proves to be the beacon of hope you are assuming what exactly should I be doing? Live under siege inside the city?

In a city where to rent a meagre 45 sqm 1 bedroom apartment in zone 4 costs me 1500 per month?
Apartments that are old with plumbing issues and that have not been properly renovated for years?
It's just easier to find another job somewhere else. Thankfully I'm a full stack senior devops with over 10 years of experience: it won't be hard to find alternatives.
I'm not going to gamble my life and my happiness especially when the odds of everything going fine look to be really really slim.
