I'll elucidate BH.
The English national Flag, the flag of St George, until a few years ago was rarely seem except flying on Church of England steples and so forth. However in recent years it's started to be used by some rightwing mobs, and people have tended to look suspiciously at it.
However over the period of the World Cup this summer the whole place blossomed with them, and it seems to have lost those overtones.
Partly because in quite a lot of situations it ended up being flown alongside the Irish tricolour, that being the other local nation in the championship.
