What the rwnjs are saying is that Jews with guns would have had to give up their chance to live (in labor camps on the occupied Soviet territories) and die battling the Gestapo (etc.) for some higher ideal of freedom or something.

Because that would have been the choice as far as the Jews would have been concerned. A chance of survival after a “resettlement” v. certain death in a fight with the state apparatus. That there would have been no resettlement is not something they knew.
