Some previous pub bannings have been because people, usually women, were wearing clothing with a "message", such as the dictionary definition of a woman as an Adult Human Female.
In my case I was initially told, when I was standing outside the pub on 7 May, that I had to take off my WDI hoodie if I wanted to go back inside and rejoin my ukulele session, also that if I turned up again wearing it that I would be asked to leave.
In the letter from the pub banning me it said (my bolding):
"On the 7th of May 2024 you came to the Cumberland wearing a hoody making a clear statement. Your name now appears as a parliamentary candidate to represent the Party of Women at Westminster, a party with which the Cumberland will not be associated. Accordingly you will no longer be allowed entry within the pub’s boundaries."
The "clear statement" was simply the name and logo of Women's Declaration International.
(I doubt that they were referring to one of Jess de Wahl's "Heretic" badges that I had sewn onto a sleeve, to hide where I had accidentally dropped bleach on to it 😬)
It is of course possible for someone to wear clothing carrying a "clear statement" that does not express their beliefs.
Examples: a retro sweatshirt lauding a USA Baseball Team or, completely by accident, something in a foreign language, Chinese characters, hieroglyphics, runes, etc. that they do not understand - or even an AHF T-shirt or a "Progress Flag" when the person does not appreciate their full significance and the various ways they might be understood by different people engaged in the "sex vs gender" political struggle.
The Progress Flag vs the original Rainbow Flag is perhaps an even better example than an AHF "Be The Billboard" T-Shirt.
I think that once upon a time everyone would have understood a Rainbow Flag hung in a pub window as a "Welcome Mat" for lesbian, gay and bisexual people, ie. not as a "Straights Keep Out" sign. Nowadays it might be seen by some as a quaint hangover from simpler times, by others as possibly deliberately "gender critical" and by others as defiantly and illegally "trans exclusionary".
There was never an "anti-straight" message with the Rainbow Flag when it was used to signal solidarity with and support for "gay rights".
By contrast, there is a good case for arguing, on the evidence, that displaying a Progress Flag on clothing or premises can signal a wish or intention to discriminate against people who hold "gender critical" beliefs. More subtle than "TERF-Free Zone" along with depictions of weapons or violence against women but a warning sign nonetheless.
I wonder how many businesses, institutions and other organisations are aware of how regressive, how aggressively exclusionary, anti-woman's rights and bigoted, the Progress Flag is understood as a "clear statement" by many people?
