Jewish ally(sorry)

Hi, I’m an Aussie Catholic and I detest the antisemitism that’s festering in Australia.

I’ve had an idea that there should be a badge, bracelet, something that non Jews can wear to show the quiet but forceful support that (I’m sure) is there in Australian society.

It might seem like more virtue signalling, but I would feel a bit nervous displaying my support, whereas I would have no fear if I was supporting most other international causes.
