I respect your opinion, but my argument against that is:
Christians and Jews cannot be considered “Ahl al-Kitāb” or people of the book anymore. Christians believe in the trinity (God, son, and the holy spirit) and believe Prophet Jesus to be their Lord and savior. That right there rules them out. Secondly, Jews these days really can’t be differentiated from Christians, even if the slaughter companies are run by Orthodox Jews, you don’t know if the meat is being cut by machines or if the person slaughtering is an atheist, etc etc.
there are a million concerns. and if halal zabiha meat is ready available, why take the risk?
