That is how I feel after the years of debate here, relived I managed to avoid it.
"Belief in God" isn't really a thing except for a tiny fraction of religious believers. Beyond that, theism is nothing more than tribalism, cultural conditioning, identity. A lot of people can realize their lack of belief but still remain religious in terms of defending religious culture and ignoring what makes religion so insidious and detrimental to human well being in the first place.
You haven't actually had conversations with religious people have you?
This view is based on nothing
but conversations with religious people. In fact, I recommend to anyone interested that they also converse with believers and ask them about that belief.
Ask them what the experience of God is like. What does it feel like? How does it affect you? You'll find they don't actually describe experiences at all, and that's because they've never had experiences of God, just experiences of other people telling them what they're supposed to believe about God.
Ask them if it's really the group identity they worship. Of course, they'll say, no, it's God I believe in. But it's the group identity they defend without fail. It shouldn't matter what you call yourself if you truly believe in a God that is real to you.
I've said for years now that if I were a religious believer, knowing how tribalistic and human-constructed religion actually is, that I would tell everyone to please make fun of my religion. Attack my tribal identity. Pick it apart, make fun, hold me accountable for tribalistic stupidity. My belief can take it. My belief in something divine and supernatural cannot be affected by what I call myself or whether you attack that label or the human-made stories about that label and claim to belief.
Every now and then you'll get someone who will claim that the experience of God is something like a peaceful calm feeling of love or whatever, and I'm sure some people do experience such things (whether they attribute them to the religion they were taught or not), but you'll mostly see people who are not in the least bit calm or peaceful or loving until you point out that they are not peaceful or calm or loving, and they will try to pretend, or more likely, get pissed and storm off.
You would think that a first hand experience of an almighty, all knowing, all powerful spirit would have the power to fundamentally change how a person sees the world, how they regard their fellow human beings, how defensive they would become when questioned about it. But no, you don't. That's a very rare thing, and to be honest, I see those transcendent experiences a lot more among religions and philosophies that Christians would view as heretical or even under the influence of Satan.
Trying to get to the truth of God belief rarely ever leads to anything but a defense of "us," our ordinary human tribe as distinct from other human identity tribes that are not like us.
