The Feminist to Atheist Pipeline

Is it just me, or is it a relatively common occurrence for religious feminists to leave their religions?

I think it is, and I call this phenomenon the Feminist to Atheist pipeline.
The pipeline in this context refers to a thing which leads to or brings about another entirely different thing or outcome.

I'll start with my story.
I became a feminist in my mid teens after Watching a Ted talk by Chimamanda Ngozi Adichie titled "We should all be feminists", some months later, I also read the book...
And soon after, I became an ardent feminist.
I became very committed to dismantling misogyny and sexism wherever I encountered them, and indeed I did this for many months and even years... but there was one area in which sexism was particularly prevalent but it was also one that I frequently avoided addressing.
What area was this? My religion; Christianity.
See, I was born to Christian parents, and I was raised in a Christian home. We went to church every Sunday, without fail. I grew up to wholeheartedly accept the religion... until I became a feminist and some of my religious beliefs started to appear questionable.
When I was a child, before I even adopted feminism, I noticed that God-ordained pregnancies in the Bible rarely produced daughters. Sarah, Rebecca, Hannah, Elizabeth, etc all had sons. I thought this was just a coincidence or that God must have a good reason for making it that way. But this was far from the only problem when it came to Christianity and women.

Once time I was reading the Bible, I came across a passage in Ecclesiastes. It went like this "while I was still searching but not finding— I found one upright man among a thousand, but not one upright woman among them all."
(Ecclesiastes 7:28 NIV)
This was incredibly disconcerting for me as a Christian feminist; it seemed to imply that women were bad and it was very hard, almost impossible to find a good woman. I found this offensive.
But it was the word of God -- or so I thought.
Another disturbing passage was the part about wifely submission. Paul, in three or four separate passages, urges women to submit to their husbands and also tells men that they're the head to the family. As I tried to decipher what these edicts might mean, the more meaningless and ungodly I found them.
I found many more similarly offensive passages in the Bible, in both old and new testaments.
After many more months of thinking and researching, I left the faith altogether.
I couldn't keep pretending that the Bible or Christianity wasn't sexist.
The fact is that throughout the entire Bible, God shows a very strong and consistent preference for men in almost everything and that, by definition, is sexism.
I don't want to give the impression that the misogyny/sexism of the Bible was the only reason I left, there were other reasons like the inaccuracies and contradictions, etc but the misogyny was definitely the major reason. The Bible has a very insulting view of women and if I wasn't first a feminist, I would likely never have left Christianity.
This isn't to say that biblical misogyny can only be detected by feminists, because anyone who studies the Bible critically would have noticed it, however it seems feminists are more likely to notice and act on it.
This also doesn't mean that every religious feminist would eventually deconvert, but it does mean that they're more likely than other religious people to find issues with their religion.
It's safe to say that feminism was the major driving force behind my deconversion.

And sure enough, I'm not the only one. I've heard a couple other stories like mine and have even read research indicating the same thing -- that feminism is often a catalyst for apostasy.

And this is what I term the feminist to atheist pipeline.
