The position of those who oppose you is that "all men" means "all men" in John 12:32, which is correct. You have said (I'm paraphrasing) it cannot mean "all men without exception". I am still lost on why you believe Jesus did not mean "all men" when He said "all men".
If you pay close attention, you will find that various people don't believe he meant what he said on numerous occasions.
Like here for example:
(where their sins will lead them) it is better for you to lose one of the parts of your body, than for your whole body to go into hell.
Therefore you are to be perfect just as your heavenly Father is perfect.
No one can serve two Lords for either he will hate the one and love the other, or he will be devoted to one and despise the other. You cannot
serve God and wealth.
But seek first His kingdom and His righteousness, and all these things will be added to you.
Whoever does not carry his own cross and come after Me cannot
be My disciple. ... So then, none of you can
be My disciple who does not forsake all that he has.
He who loves father or mother more than Me is not worthy of Me; and he who loves son or daughter more than Me is not worthy of Me. 38 And he who does not take his cross and follow after Me is not worthy of Me.
24 Then Jesus said to His disciples, “If anyone wishes to come after Me, he must deny himself, and take up his cross and follow Me.
25 For whoever wishes to save his soul
will lose it; but whoever loses his soul for My sake will find it.
For any one of those verses, there are many who don't believe he meant what he said. And many more of his teachings. But you will find those same people know how to make up excuses to dismiss what he said. Jesus' teachings are easily dismissed when men don't like what he said.
