Positive and negative symbology has been used by the human race for hundreds of thousands of years. Focusing on how each pair of images makes you FEEL... which one feels more positive?
And just ONE more... As the founder of Peace Positive™, I know I'm may catch a whole lot of heat for this one... but in my opinion, IT MUST BE SAID. And no, I am NOT anti-Jewish or anti-Israel (although I may not particularly like their actions lately)... or "anti-" anything. I'd rather be "pro-" something. Like "pro-equality".

Not that it stands for something "negative" per se (it's actually a beautiful symbol)... but rather... INEQUALITY vs EQUALITY.
