npub1j8m6n55er97404gz59f35yt7h22lqh9dk5algdxlnza90paca7hsk5v5r7 (npub1j8m…v5r7) I mean, not for nothing, and I’m sure you won’t believe me, but the story you tell about the pin is the story the Israeli marketing department put out. The real story: the origin of Red Hand symbolism actually dates back centuries before Israel's occupation.
Academic sources for origin of the symbol:
Ulster University’s CAIN archive link on origin of Red Hand symbol: https://cain.ulster.ac.uk/images/symbols/crosstrad.htm -University College Dublin news article on Dr Benjamin Hazard’s award winning paper “at Ó Neill’s right hand: Flaithrí Ó Maoil Chonaire and the Red Hand of Ulster, 1609-29”: https://www.ucd.ie/news/2009/08AUG09/070809_history.html
Not only that, the US used the same symbol in Ww1. https://www.ima-usa.com/products/original-u-s-wwi-liberty-bonds-propaganda-poster-the-hun-his-mark-blot-it-out-19-x-30?variant=40566142861381
