I think the kind of purely emotional reactionary hatred of religion does exist as described in the OP and can be a short-lived transitional phase. However, I think there is also a more intellectually grounded disdain for religion rooted in reasoned understanding of the inherent harm done by authoritarian monotheism rooted in irrational faith. The latter is more long term and sustained b/c the more knowledge one gains about religion and it's historical and current impact on society the more negative and harmful religion looks. I'd argue that someone like Dawkins is the latter and that most so called "militant atheism" is mostly just honest, rational, and warranted objections to the intellectual and moral that religion does.
I was raised moderate Congregational protestant, then my dad remarried to a Catholic and I was forced to attend a Catholic school in 6th grade (until I got kicked out), and attend Catholic mass and go to "youth groups". I consciously rejected Christianity in my mid teens based a little bit on finding it absurd, but mostly b/c I thought it's teachings were bigoted and immoral. I remember also thinking that the Jesus cursing the fig tree b/c it had no fruit made Jesus look rather petty and narcissistic. For the first 5 years or so (till early 20's), I didn't really focus much energy on Christianity but rather looked into other religions and philosophies (Taoism, Buddhism, Native American spiritualism). Although I found eastern philosophies far more appealing than monotheism, I ultimately realized that I didn't need or buy into any form of "spiritualism". In the 25 years since I studied history, politics, and human psychology and behavior and began to understand more and more the negative impact of monotheism and faith-based epistemology on forms of human progress (intellectual, political, moral). As I became more politically aware and active, social progress became more important to me and thus the enemies of progress (of which religion is one of the greatest) came into sharper relief. This is reinforced by the fact that I am well aware of the empirical data that links degree of Abrahamic religiosity to many negative elements of society, from climate change denial to misogyny, homophobia, racism, and authoritarian disdain for real democracy. And these things are not some abuse or distortion of Abrahamic religion, but an inherent byproduct of it's core assumptions and values within it's founding doctrines. The negative association between level of religiosity and these negative social/psychological forces is reliably observed whether doing comparisons between individuals within a single community, within a community over time, between different communities or US states, between types of regions (urban/rural), or between countries there are a reliable association.
Sure, most of what you have said has some basis in truth, imo, but do you honestly find liberal versions of religion to be harmful? Take Politesse, as an example of someone who enjoys liberal religion. Hope he doesn't mind mentioning him. He has labeled himself an agnostic Christian, finds some enjoyment in a variety of religions, and has mentioned that he attends or has attended a UU fellowship, which gave me the impression that he's inclined to like the principles of Unitarianism. I don't see that type of religious belief as the least bit harmful. In fact, I see it as beneficial for many people. I cold easily fit in with a UU fellowship, assuming it was a very diverse one, including diversity of belief. I have never lived near one, so it's not a possibility, but I do like Unitarianism in principle. I do see some value in some of the myths that humans have created. And, to be very honest, I don't understand why some atheists put that variety of religion in the same pot as the more conservative, extremist versions of religion.
And, there are so many good, loving, generous, religious believers, there must be some benefit that they receive from their collection of myths. I'm not making the claim that religion always reflects or influences one's morality, but I do think it can in either a positive or negative way. Just look at the crazed evangelical Christians/QAnon idiots who invaded the US capital building on January 6th. That would be an example of the negative impact of extremist religion.
The opposite extreme might be Unitarians who promote social justice as a group, or how they open their doors to offer holiday dinner to the lonely in the community etc. Just because they are both forms of religion, doesn't mean they have anything in common. One promotes a narrow minded mythology that can promote violence under certain circumstances, and that also distances itself from anything resembling reality. The other promotes diversity, generosity and justice, while not taking any one set of myths too literally. It's hard for me to imagine a UU willing to kill or die for religion. I just don't think it's fair to put all of religion into one basket and then label it based on the worst parts. I guess we just see things from a different perspective.
