🏴☠️I made a design for a pink pony patch for someone but he changed his mind so I figured I'd share it here in case anyone else wanted to make patches or stickers with it. Nothing fancy but I thought it was fun.
Juho MäntysaloThank-you for the idea.

@XenoPhage @iju No problem. I figured it could explain it better than I.
I did have a short explanation in the alt-text, which I'll repeat here with some clarification: they are the three arrows (as in: from a [cross]bow) to strike at the heart of ideologies against peoples' self-determination: capitalism, monarchism, and vanguardism [eg. Soviet communism].
It's a symbol that's used by antifascists, socialists, anarchists, and left-leaning social democracts.
EDIT: It's a very good thing you asked. Asking questions makes us all smarter :)
