As with the Cool Britannia movement of the '90s when the Union Jack became a symbol of much of that, a couple of decades before, it was also in evidence as part of the mid sixties Swinging London scene. I can remember my 13 year old self and friends walking around with Union Jack carrier bags, there was certainly no association at that age with a nationalistic fervour it was, as with Gerry Halliwell's dress, 30 years hence, a mere fashion statement.
My step daughter has a next door neighbour who has a Union Jack flag in his garden, she reacts to that with much eye rolling, and although she and I get on really well, she is at times intolerant of other people's foibles. Because that's all it is with him, he is quiet mild mannered person, a little old fashioned maybe, who evidently likes the flag. Personally I have no inclination to stick a flag pole and fly our national flag in my garden, it wouldn't be my thing, but I defend the right of others to want to do that.
Posters have commented, depending where these displays are, they could be a distraction for the motorists. I can see that point also. In fact when I've seen the rainbow crossings rolled out at various points around the country, my feelings are "absolute over the top lunacy and a complete distraction for the motorists and quite possible unsafe, in moving away from the traditional black and white denoting a pedestrian crossing could lead to accidents because of their ambiguity. Why and what are they there for?" I have no problem with anyone else's sexuality and thank goodness they have equal rights now when they were an oppressed minority, but when I enter a business such as shop or building society, I don't wish to be reminded of the fact that they are supporting Pride, it's irrelevant to me as a customer. There are a lot of other people who have suffered at the hands of others in their lives, children who were abused in state care, girls who were and have been trafficked to name but two. Where are their flags and regalia.? The whole Pride month has become a massive never ending, cause celebre, in the way councils and businesses have shoved it in everyone's face. Pride/Palestinian/Ukrainian/regional or even as one Birmingham resident posted on the deleted thread, other nation's flags, such as the Pakistan one. So why not our own national flag then? I think at times there has been a reluctance even on official buildings not to fly it, just in case in some bureaucrat's eyes, "it might just cause offence" There has at times and in some places in the country been a suppression of an overt display of national identity and I'm afraid there's a perfect storm right now of anger surrounding all of that and the perception that some feel second class citizens in their own country in the way they are ignored. In some instances, not all, there has been a racist overtone. Simultaneously there is this justified reasoning, lets reclaim the national flag, without the racist connotations, but as a symbol of pride and national identity which is very prevalent in the visibility of flag flying in other countries around the world.
