Kike is a slur invented by Christians
Kike is short for kikel, which means circle. This is a slur because American Christians noticed jewish immigrants hated Christ so much they refused to write T, X, or +. They instead wrote in a circle "O".
hence the kikel, eventually becoming just "kike."
so based on the etymology that makes them a kike since they reject and slander Christ just like the original kikels did
