OK why do you say Prager is going to hell?
I personally don't think he is going to Hell. But the worldview of the New Testament is that he is going there since he is Jewish and so doesn't accept the Christian God. I assume he would not endorse a worldview that advocated for his being tortured for eternity.
Jesus Christ said the only way into heaven is to be born again, meaning that you turn from sin and turn to Jesus Christ as your savior. Dennis Prager and anyone else who has not done that, according to Jesus Christ, is going to hell. That is who your argument is with.
I would strongly suggest reading the new testament, which is essentially the story of Jesus Christ. Read it with as open a mind as possible and realize that either Christ was a lunatic, a liar, or he was telling the truth.
