You just won't see past your prejudice and actually hear what people are saying.
The people campaigning for an end to genocide are not doing so because anyone is Jewish, Muslim or anything else. It is because people have empathy and can identify with how they would feel if it was their dad shot dead in the street trying desperately to get food for his starving family, they can imagine how they would feel if it was his bleeding body on the ground, him in pain, him they would never see again. They can imagine how they would feel if their small child had become mute, so traumatised by seeing people die and injured around them, living in mortal fear so long they have lost the ability to speak. They actively try and imagine how they would feel if it was their tiny baby lying lifeless on their arms, after 9 months of pregnancy, all the hope and excitement, only for their tiny life to be cut short.
I am not saying Hamas aren't a religious group, they have come about primarily as a resistance to the oppression of the Palestinians. If it was not them it would be someone else, because you can't systematically abuse an entire people for decades and expect them not to fight back. If they are electorally disenfranchised and have few rights under and aparteid regime, you are likely to see violence in the approaches and there will be people in the oppressor's group hurt. Obviously a small fraction of the number that are hurt in the oppressed's group.
Nobody fighting for an end to the genocide is doing so because those perpetrating it happen to be Jewish. They are fighting because genocide is evil (I need a stronger word but can't think of one).
