I have a Unison hat (well, actually more than one) and once someone tried to snatch my hat off my head, but I can't remember if I was wearing my Unison hat or a non-union related one, and either way I think it was more to do with them being a pissed antisocial twat who thought snatching a stranger's hat would be funny than because they were outraged by trade unionism. I also have a UCU hat I won in a pub quiz once, and I was going to say that I think one of my friends said that they liked it but it didn't go with my sunglasses, but on reflection I think they actually said that about a top I was wearing (similar hot pink colour, no union-related branding though). I've never worn a MAGA hat in Central London, so I've never had any negative reactions on that score though.
Has anyone else not worn a MAGA hat in Central London, and what sort of reactions did you not get if so?
