The Judeo-Christian god, as described in the bible, is one of the most evil creatures I have ever read about. He comes off as a tyrannical dictator. He punishes all of humanity for the sins of Adam and Eve. He created hell, and sends billions of people there, simply for believing the wrong book. He commits countless atrocities and acts of genocide in the bible. He causes so much unnecessary suffering. He blames his creation for being the way he created them. And above all this, he demands to be loved and worshipped by the very beings that he created.
Why would anyone with an ounce of integrity worship such an evil creature?
There are several claims here that are certainly not part of the Hebrew Bible, or if they are they are minor, negligible and open for interpretation. For example the Hebrew Bible hardly mentions an afterlife. You might mean that the New Testament joint with Christian dogma does. Likewise Original Sin is for the most part a strong point of Christian dogma.
So it's somewhat of a caricature to fish concepts from the New Testament and Christian dogma and glue them on the 'Bible' or a 'Judeo-Christian' God.
As for other passages from the Hebrew Bible (the so called 'Old Testament'), for example war, if you look at all cultures of the world (at least the interesting ones), you will find they have gods of wars and chief gods who engage in warfare or in human affairs. While I do not necessarily adhere to the Bible or the Biblical God, I find that the Biblical version is more advanced in many ways.
The Scandinavians had their Thor and Odin. The Greeks had their Ares, Athena, and Zeus. And the Hebrews had YHVH and the Bible, which I find to be packed with much more moralistic and humanistic aspects than the Olympian or Norse versions (as much as I love them both).
Sure if you filter the entire Bible, and leave out the prose, wisdom and love poetry, Prophetic writing, the Psalms, Ecclesiastes, The Song of Songs, the Proverbs, and hundreds of other pages and only focus on paragraphs which discuss strife and war you might have a point. However the Bible has many inspirational, aesthetic, moralistic, poetic and literary qualities that have inspired hundreds of years of Western art, literature, and philosophy.
So while people may not need to worship the God of the Bible in this day and age, they should at least have some basic grasp of the text and get off their high horse.
To summarize. I do pity you if all the people around you worship a Biblical God who represent all the things you described above, such as the sinful nature of man, or the fire of hell. It's not the first rant of this kind made on the forum or the internet. To my assessment, these rants usually come from people who have been surrounded by fundamentalist Christian dogma and have been scarred by it. Many other people have another experience, have not been drilled with the prospect of ending up in hell, and have a healthy education of the Bible, Biblical inspired English literature, Biblical inspired Renaissance art, or Biblical inspired chapters in European history.
Obviously we see different things in the Bible, and people like myself are much less interested in supernatural beliefs about the text, with or without a dictator god.
If ever people want to seriously discuss scriptures, they need to release themselves from their indoctrination first. Discuss the Bible without the relevance if God exists or not, and without taking at face value miracle making. These are all theatrical aspects of a much more multi layered text.
