Christianity is not the only religious "cult" where there is an overwhelming majority of false members. Truth/reality is a very rare commodity, accessible to only a select few, if that many.
As echoed long ago, "Many are the wandbearers but few are the mystics."
And He went through the cities and villages, teaching, and journeying toward Jerusalem. Then one said to Him, “Lord, are there few who are saved?”
And He said to them, “Strive to enter through the NARROW gate, for many, I say to you, will seek to enter and will not be able."
To be Saved, the mark of approval, requires a lot of hard work, blood, sweat, and tears.

I guess that would include the opinion of the possible last human alive after an all out nuclear war.
