I think there's more to it than just that center symbol, from what I'm seeing. The little clovers look like the cross pattée of the Knights Templar, and if you look at the dots in between those crosses, maybe it's just a stretch, as I'm not sure if I'm just seeing things, but I think they form a pentagram. Also, I looked up who the design executive was who did the designs on the cookie, William Turnier was his name, and it looks like there's talk of him being involved in a Masonic order, but I can't find any solid proof of that as of yet. Oh, and finally, it looks like we've got to wrap it up and go home, guys. It's so over.
Snopes fact-checked this already, and they put the red image on the page, so that means it's all false, everything about it. They literally just say
>If, in fact, the Oreo's designer was a Freemason, so what? If, in fact, there are esoteric symbols on the cookies, so what? If the presence of those symbols isn't coincidental, what are we supposed to make of that? What's the point of putting them on a cookie?
as in
>Okay, well, if this IS true, you freaking conspiratard bigot, so what? Why should I care? You're being irrational, shut up and eat your cookie.
