We should investigate what is being taught there only because we are spending money on educating the Palestinian children. If they are not teaching things that line up with our values, there’s no justification for funding it. Arguably, we shouldn’t be funding their schools at all regardless of what’s being taught - the schools here is the US are doing a poor job of educating our own kids, why are we spending taxpayer money on educating kids in a country on the other side of the planet that hates us and our values?
