Not sure what you are, but I would bet ,someone with a Muslim background who studied in a madrasa. Your opening monologue gives you away as not Christian. Neither the old or new Testament mention Palestine or Palestinians and when Jews came to the land it was called Canaan. The Phillistines were actually Greeks and both disappeared about 3000 years ago. I am sure that if your sister in law was Jewish , you would be shunned by your brother and his wife and I am also sure you have Jewish friends who agree with you(LMAO)
You are the run of the mill mooslime Islamofascist Antisemite with very little between your ears
Look up the Palestinian flag from the 1920’s and maybe it will be an awakening experience.
