The fact that people are trying to claim to be the original isrealites is actually a good thing because it means they are desperate for their religion to be true. It also means they recoginize jews as the enemy. All I would push in a arguement is that the bible calls blacks the beast of the fields. Against whites, that our ancestors claimed to be the children of the Gods who are the fallen angels in the bible. Just to make it more fun hit the general christians with miscegnation being a sin (seed of adam and all that). Many christian are okay with race mixing which is punishable by death in the bible. Sow racial in fighting using the bible, in trying to prove themselves right they will prove the bible wrong. Never quote scriptures just make a claim as a matter of fact and walk away. If someone gets angry just say you didn't write the bible and you are not a christain. You can also pretend to be stupid and ask uncomfortable questions about the bible.
Its pointless arguing with radicals.
Race mixing isn't forbidden in the Torah or New Testament, the oppositte actually.
The NT teaches "in christ" there is no jew or gentile, greek or barbarian, meaning race/ethnicity doesn't matter.
Moses married and had children with a Black woman, a Kushite. 2 jews complained about it and Yahweh defended Moses and cursed the jewess Miriam with leprosy.
Jews were only forbidden from intemarrying with the Caananite tribes they were conquering/destroying. Nowhere in the Bible does it say races can't mix.
So yeah, Christianity cannot defend Whites in any way since in the ideal Christian World, there would be no races or the concept of race wouldn't exist or matter at all. Also the jew Paul said he wished all Christians were celibate like him which means no one would be having kids either, aka what the jews and the NWO want for us, to not have sex or children. Marriage is only a concession in Christianity, not an ideal.
Corinthians 7:1-7
"Now for the matters you wrote about: “It is good for a man not to have sexual relations with a woman.” 2 But since sexual immorality is occurring, each man should have sexual relations with his own wife, and each woman with her own husband. 3 The husband should fulfill his marital duty to his wife, and likewise the wife to her husband. 4 The wife does not have authority over her own body but yields it to her husband. In the same way, the husband does not have authority over his own body but yields it to his wife. 5 Do not deprive each other except perhaps by mutual consent and for a time, so that you may devote yourselves to prayer. Then come together again so that Satan will not tempt you because of your lack of self-control. 6 I say this as a concession, not as a command. 7 I wish that all of you were as I am. But each of you has your own gift from God; one has this gift, another has that."
So yeah the Bible gives a big thumbs up to both celibacy and race-mixing, but xianity is the "only hope" for the Whites according to these clowns.
