The problem is your building (the "mortar" you use to hold verses together to form doctrine).You should know because you have come down with a bad case of it. I don't build any doctrine on "necessary implications" but explicit clear statements and then only support that with implicit texts. This is particularly true with Penal Substitutionary atonement. Penal is clearly stated "judged according to your works" and "by one man sin entered the world and death by sin" as "sin is the violation of the law." Substiutionary is clearly presented in Levitical Law "for the people" and "because of their transgressions" and "for an atonement." The sacrificial animals that atones for sin is explicitly and clearly applied to Jesus Christ "the lamb of God that taketh away the sin of the world" and "without spot or blemish." Clear explicit language.
No one is denying that Christ is the Lamb of God that takes away the sin of the world. No one is denying that Christ bore our sin. No one is denying that the OT system looked to (as a "type") of how God would bring about redemption to man. No one is denying Christ as our "High Priest". No one is denying it was God's will that Jesus suffer the cross. No one is denying that sin becomes a transgression in face of the Law. No one is denying that Christ died so that we would escape the wrath to come. No one is denying that Christ is the "Last Adam". No one is denying that we all will be judged according to our works (what Peter tells the Church - not the world). No one is denying that by His stripes we are healed.
But I, along with many other Christians throughout the history of the Church, am denying that God punished Jesus in our stead.
I understand that you don't "get it". I understand that the fact other ideas of the Atonement have existed throughout history by Christians who affirm the same Scriptures is just beyond your grasp. I can't help that. I can only tell you that you cannot debate the Atonement with blinders on. You cannot engage other people while oblivious to the fact your interpretation is not "clearly" stated in the biblical text.
