It's not what you know --- it's what you reject that tells the tale.
Satan knows Scripture up one side and down the other. He rejects it.
One cannot reject something that is not honestly offered. If God has created you with an inability to accept an offer, then you have no ability to either accept it or reject it. So utilizing that as a basis, the only people who could possibly reject the gospel are the elect! But they cannot reject it because the grace that is offered is "irresistible." Since it is impossible for them to reject it, it is not "offered," it is foisted.
I think you need to use different terms than "offer and rejection." Those terms have specific meanings and the way you Calvinists use them is inconsistent with their meanings. The non-Calvinist understands that God truly offers salvation and that those who perish are those who truly reject it.
I think the proper Calvinistic terms to use are "foisted" and "hidden." Salvation is "foisted" upon the elect and "hidden" from everyone else. You may not like those terms, but they are clearly a more accurate rendering of your theology than "offered and rejected."
