Did you realize that Christianity doesn't make sense? Please Answer. (Don't read if easily offended.)?

If you're an Arab and believe the bible. Then you must also believe you are a bast... I don't wat to be rude but it says in the bible that Ismael was born out of wedlock and his father abandoned him. And if you're a Jew and believe in the bible then you must also believe that you are inbred. Because Sarah was Abraham's sister. And what kind of Prophet would do this? Aren't prophet's supposed to be good role models? And if they are just like other people then that must mean I am a prophet. LOL. It doesn't make sense. But the real Question is why would a middle-eastern person believe this? Arabs are bast@rds and Jews are inbred according to the Bible. And how are Jews the people of God if they are inbred. SMH.
