I actually think that this is an interesting question.
I can’t speak for anyone except myself, but I speculate that it depends upon what one’s focus is. Some people are atheistic because of abstract or philosophical reasons, while others (such as myself) are more concerned with practicality.
In my case, I see the real harm and damage that’s done by religion, and I wish to have a forum to vent and explore ideas about how to remove and/or weaken the influence of religion in society.
I–for example–often throw out the Brescia church explosion as an example of the harm done by religion. Another example is how it was an affront to God for a doctor to wash his or her hands in bleach water (to prevent infections like childbed fever) before attending a woman in labor, as Genesis states that God will greatly multiply Eve’s pain in childbirth as punishment for tempting Adam with the fruit of the tree.
If you are looking for a more modern context to challenge my points, then consider that I have been professionally disciplined (in my job as a paramedic) for treating Wiccans, Sikhs, and people who practice Santeria with the same respect that I extend toward Christian ministers, Catholic priests, and/or Jewish rabbis.
Also, the religious values of certian hospitals have caused them to complain about me to my bosses when I refused to discriminate against gay people . . . an example being when I treat a patient’s other half like a spouse.
See below for examples of what I’m talking about:

I have been kept from promotion and advancement because I insist on extending the same accomodations to every religion . . . even if such religions (like Wicca) are “wrong” or “dangerous”, as I flatly refuse to discriminate in my professional capacity as a paramedic.
As another interesting example of how religion hurts people, consider snake handling.
There are churches in this country where people handle venomous snakes as a part of the service. Please see below:
When it comes to snake handling, I see an interesting contradiction: The conservative right claims that drag shows and LGBTQ people are dangerous to children, because if children are exposed to gay people, then kids can turn gay because they might emulate the behavior.
Well . . . I have run emergency calls on children who were bitten by venomous snakes (usually a dangerous water moccasin, which has the latin binomial of Agkistrodon piscivorus) because they were emulating what they experienced in church.
My point is that Christians will protest against LGBTQ people for the sake of the children, yet they won’t protest against snake handling churches . . . when kids die because they emulate what they saw a minister doing.
These types of issues are a part of why I’ve become active in atheism . . . although I prefer the term “religious skepticism” over “atheism.”
Does any of this clarify things for you?
