“Then all non Christians are Satanic.”
The verse is about judging messages that purport to come from the spiritual realm, not about judging people. However, all other religions that purport to be based on spiritual revelation do indeed come from Satan, God was clear enough about that. Judaism of course was originally based on a true revelation from God, but modern Judaism subordinates that revelation to the Talmud, which did not come from God.
“Insulting Sihks and Jews united with Christians in the fight against Jihad is a bad idea.”
I don’t think you are going to have much luck asking Christians not to speak the truth in order to avoid offending people. God’s truth is always offensive to those of the world, it is meant to be that way:
“22 Seeing that Jews ask for signs, and Greeks seek after wisdom:
23 but we preach Christ crucified, unto Jews a stumblingblock, and unto Gentiles foolishness;
24 but unto them that are called, both Jews and Greeks, Christ the power of God, and the wisdom of God.
25 Because the foolishness of God is wiser than men; and the weakness of God is stronger than men.” 1 Corinthians 1:22-25
I’m sure you’re aware that Jews regard the Talmud as Oral Law, passed down, generation to generation from Sinai.
