What you're not addressing is that religious belief carries with it a whole host of threats that have eternal consequences. Religions create a number of genuinely unsolvable dilemmas. The ideology/dogma purports that there is a source material that lays out the belief system. The ideology/dogma claims this source material has a level of functionality that supports that belief system as well.
The major Christian denominations (i.e., the vast majority) do not threaten other faiths (or atheists) with hell. They simply entrust those with different beliefs (or no belief) to a loving and merciful God. The majority of Jews do not even believe in hell.
It is not reasonable to go in search of a minority, splintered denomination and then broad brush the majority with minority practices and beliefs.
The foundation of Judaism and Christianity is that God loves each individual and that we are called to love God and our fellow human beings. Christianity teaches that our sins
are forgiven--and that we are called to forgive our fellow humans. Orthodox Jews strive to remember/bring God's presence into every aspect of every day life.
This is a very simple foundation, and we all fall into the trap of complicating it. It starts with two simple questions? How do we love God? How do we love our fellow man? In giving sincere examples, the ancient Jews provided 613 laws. Now consider those 613 laws each prompting another question which prompted another 613 example.... As you can see, loving God, and loving and forgiving one's fellow man quickly became complicated.
It degenerates into this or something similar: "I don't believe God would torture good people in hell for an eternity because they are not of a specific faith. Therefore, I do not believe in God."
Wouldn't a more logical statement be, "God is loving and forgiving, therefore I don't believe He tortures anyone for an eternity."
