So here is the deal. Some of the people walking around Palestine, Gaza, and the West Bank are blood relatives of Jesus. Distant blood relatives, but still blood relatives. Given 2000 years, it is possible that the vast majority of present day Palestinians are remote relatives of Jesus.
Israel is killing them.
And YOU are paying for it, which means you share the guilt. YOU are paying for the weapons used to kill the modern day family of Jesus. The moment you sign that 1040 form, you sign a confession, admitting before all the world that you are an accessory in the murder.
