I have to laugh about the fact that half the flags are the wrong way around so here is a friendly guide.
It assumes the flag pole is on the left by the way.
You think any and all instances of a country's flag being flown means the person who put it up is racist? That seems like a bit of an extreme opinion.
Where I am, I see plenty of Scotland/Northumberland/Ukraine flags, interspersed with the occasional UK, England, and Palestine flag. Are all of these people who raised these flags racist/bigoted?
