No, I’ve never seen a Star of David (hexagram, geometrically) in the recycling symbol until just now, when you suggested it.
OK, if you look at the negative space / ground behind the figure, there’s an imperfect 6-pointed shape but the dominant symmetry is 3-fold / 120 degrees. There are 3 arrows folded in space to form an equilateral triangle—a pretty fundamental graphic / spatial element.
Yet what if we agree that, on further scrutiny, there’s an embedded Star of David in the recycling symbol? Is it a deliberate, intended message? Might it betray the presence of a Jewish / Zionist / pro-Israel / Liberal / Commie / Leftist / Anarchist / New World Order / anti-Christian conspiracy? (In this scenario the bad guys, eschewing discretion & subtlety, drop this well-observed hint to their identity.)
Perhaps it’s a subliminal technique: You’re not supposed to see the Star of David but it nonetheless insinuates itself into your subconscious: Buy Israel bonds. Contribute to United Jewish Appeal. Become a rabbi.
Get real, lol
In your own words: …nothing at all and a mere coincidental thing that happens in the presence of triangular shapes.
