1. Being in Britain, you either hang the Union Jack or nothing. There is no reason to put political activist flags there. Even the original rainbow flag has political activism (from the US) at its core. This is similar hanging the Gadsden flag, hammer and sickle , swastika, fist whatever. There is a time and place for this, but this isn't in public on public property.

2. It is foreign ideology taking enforcing itself on the British public. And its anti-British.

And then finally the flag itself:
3. If you look at the history flags itself, the background of it is that it came from a grass-roots organisation with the colours symbolising aspects of what the creator thought everybody possessed: sexuality, life, healing, sun, nature, art, harmony, magic, soul. That kinda stuff. Very generic, all the people are included. Rather wholesome when you think about it. And then academia gets involved and you see this flag instantly getting co-opted and suddenly the extra stripes are BIPOC and people with AIDS. (Going by this logic it implies BIPOC and HIV patients aren't people or even human. Nice one! ) You have simple and generic words that compose a human being, and suddenly from the top down you get academic trash tacked on to this and it completely seems out of place.

I forgot what the circle is about, but it was something equally cringe and not fitting.

Ultimately I don't care about they LGBT, but in the sense that they can do whatever they want (with consenting adults), as long as they leave me alone. (Except the T's, I've got the hots for a few 🥵 )
