King Sooper is a Kroger branded store and part of a national chain, not some Jewish specialty shop.
All Kroger branded stores are called ‘kosher friendly’ on their websites, not just the one in Boulder Co.
There is nothing overtly Jewish about King Sooper in Boulder.
The fact your “news” source has a well known bias against Muslims might have something to do with this false narrative.
It’s clearly situated in a Jewish neighborhood and it would be safe to assume that there would be a high concentration of Jews inside. If a supermarket that was situated in a black neighborhood was attacked by white guy, we all know what the narrative would be. And if he executed his attack 5 days before Kwanza? He picked a target that was about 25 minutes away from his home. It was a kosher supermarket in a Jewish neighborhood. He carried out the attack while there was a high likelihood of there being large numbers of Jews shopping for passover. Go ahead and offer me another more plausible reason for his target selection.
