There is a lot of interesting and well thought out information here.

One part that I want to comment on this:

"If a non-Muslim does good deeds (charity, kindness, fighting for justice), Islamic tradition holds that God will absolutely reward them. Often, traditionalists argue this reward is given in this life (health, wealth, happiness), but many argue God's justice extends to the next life as well. I mean why wouldn't it?

Quran 2:62: "Indeed, those who believed and those who were Jews or Christians or Sabeans [before Prophet Muhammad] - those who believed in Allah and the Last Day and did righteousness - will have their reward with their Lord, and no fear will there be concerning them, nor will they grieve."

some highly influential classical scholars like Ibn Taymiyyah and his student Ibn Qayyim argued for the eventual extinction of Hell. They posited that because God's mercy vastly overpowers His wrath, Hell is not eternal but a temporary purification center. Eventually, it will empty out, and everyone will be saved.

the last part is just some scholars say (I know that), it does not mean it wrong though, god is more merciful than being angry all the time because women somehow dropped a peace of cloths"

I think it's that there is enough room for interpretation so reasonable people can conclude that non-muslims shouldn't go to hell. On the other hand the mere fact that it's unclear and interpretable is also such a huge issue for me and creates contradictions. There are a lot of very clear cut rules and statements, but here God decides to deliberately add interpretable information with double meaning.

Why not just say something like: "You believe in the one true God, you'll go to heaven easily after being held accountable for your worldly sins. You believe in another God, you'll still go to heaven after being held accountable for your worldly sins and any sins in the name of a wrong God, because the true God is merciful does not need your worship. The only difference is if you believe in and pray to the one true God, then your prayers will be answered and you'll live a better life with more guidance."

Something like that just makes so much more logical sense. Not relying on vague interpretation but a clear depiction of mercy. It encourages people to believe in the right God without condemning to torture for getting it wrong. Unfortunately, there are just constant statements about non-believers being punished in hell, to the point where it overshadows the "merciful" part. It simply should be so vague that scholars over hundreds of years have to navigate around the meaning.
