The Aztecs were not ‘Indians’. That is historically a factual mistake Columbus made when he reached Central American Islands thinking he reached what he called ‘West Indies’. The Aztecs were the ‘Aztecs’ a very religious tribe in north America NOT India. Even though Columbus’ mistake is still live and well, calling Native Americans ‘Indians’.
TORAH really includes Neviim, Ksuvim, Mishnah, Talmud…. In Yirmiyahu it says ???? ??????? ????? ?????? . Rachmaniyos means they didn’t become barbaric despite ????? ??? or maybe according to you they did. If so, having the torah had no impact on their actions so what is your argument?
According to PETA the whole concept of ‘Korbanos’ is barbaric. If you want to fight against the ‘barbaric war’ you will end up in hot water.
If this is really so terrible and against the Torah, a religious jew will move away for the sake of Torah. But the fact that they give permission for people to choose doesn’t yet mean it is obligated to choose to do so. Since there is no obligation to choose to end life this way there is no fight.
