Christianity is an Eastern religion. Jesus was Eastern. Yahweh was Eastern. The original one God, Ahura Mazda, is Eastern. pffft, the attitude of most Europeans today about Italy, Greece, the Balkans is as Eastern, even though they created Europe. If you listen to the music of Italy and Greece prior to World War II, yeah, Eastern.
Are you familiar with any lines about dogs in the Bible? Don't worry, nobody else is either.
Why do you think Muslims despise them? You think they came up with that attitude alone, and that by coincidence it just so happens to be the Bible as well?
Same God, same dogs.
