I don't think you can take back what wasn't yours. Obviously I'll be called the oddball here, but I didn't grow up in a UK that needed to fly a fucking flag ever five fucking feet.
We might have had a discreet one secreted somewhere at high school. And I have vague memory of one in the classroom at primary and possibly middle school.
If there was one flying at the civic centre I don't recall. Certainly there wasn't one at the DVLA offices that were nearby.
The local TA brigades had one.
Beyond that, the most I've seen a union flag is when I have been setting up systems and it's shorthand for "GB".
So my growing up was in a land where the patriotism was more powerful for being understated. With a sense of "Gawd help anyone who doubts it".
I have no desire to exchange that for a performative flag-wanking ceremony by people who use it to disguise the fact they despise the history of Britain and those that know it and adhere it it.
I'll be honest. These days, if I see a flag, I do wonder how it would sparkle under (ironically) blacklight.
