Sometimes it's necessary to use the distinctions they themselves use when referring to themselves just to keep track of who is doing what. They're not all doing the same things, and they don't all have the same agendas, although the Christian and Jewish extremists are more aligned in their beliefs and practices than either is with Muslim extremists. But the harassment of people who aren't Christian in the US military is being done by people calling themselves Christians only, and they are harassing Jews (among others), so it's very clear that the extremist Christians are not aligned entirely with Jews of any sort. And the extremist Jews are treating the Christians in Palestine no better than they are the Muslims there, to it's also clear that the extremist Jews are not aligned entirely with Christians of any sort either.
