I don't believe in god, but in absence of religion, many atheist completely miss the point of its necessity and as to why religion (or to be precise: spirituality) is such a fundamental thing that the average person needs.
The whole reason religion is so successful is due to its ability to create clear value and meaningfulness to existence and personal development. With the west becoming more increasingly secular, it's no wonder how many who abstain from religion utterly fail at finding a spiritual replacement, and thus we end up with half-men obsessed with some fandom or their political beliefs, and latch on to them as their new religion.
The overwhelming majority of humanity does not practice personal philosophy, or spirituality without a religion to back it up, and if they cannot have a god, they will have something else, as they have no agency over their own beliefs.
What I've come to learn is that people will almost always be religious (god(s) or not), the important thing then is what exactly they are religious about. Politics or even worse, a faggy fandom, does not account for spiritual meaning or personal development, thus the state at which we are today.
