Speaking of Aimee's blog... Something I've noticed about Aimee Byrd and Rachel Miller is their defensiveness. They wrote books which were overtly polemical and then acted surprised that anyone would have the gall to disagree with them. If anyone says, blogs, or tweets a word against them, they have to respond with a tediously long blog post rebutting every one of their opponents assertions. I haven't encountered this in many other writers.
One other thing one can't help but notice is their self-promotion. Whenever they post anything online, they have an image of their book as the cover. Just go to Ref21 right now and count the number of times you see the cover of Aimee's book. It's a bit off-putting.
Are they overly defensive? I think what they are surprised about is not that people disagree with them, but rather the things some people say about them, for instance the accusation that Aimee only kicked off the ESS debate in order to sneak in feminism or some such thing into the church.
Frankly, I think the overly defensive ones are those who hear about a book being published by Aimee that they suspect they may disagree with and then jump in making noise about ulterior motives.
This often happens before books of hers have even been published, and even after by people who have never read a single page.
On the subject of responses, I usually only see them respond to say, a short article or review, with a short article of their own. That's seems to be a reasonable response.
I mean there's no number of theologians and authors online who write articles responding to articles responding to articles. Essays in theology journals are a whole other story. Try looking up what Calvin taught on union with Christ and how that relates to justification/sanctification(for instance) and you'll see what I mean.
And those would be the more reserved examples.
Not to mention people who spend all day arguing on Twitter. Aimee doesn't even tweet that much. I'm presuming you don't use Twitter, because there are much worse examples.
Moreover, if you want "defensive" there are definitely other places to look.
I really cannot see how they are an exceptional case.
Regarding their books, that seems to be rather subjective. Most Christian websites have books written by people there. I mean go to Ligonier, Grace to You, Desiring God, or TGC and count the number of books that appear. And honestly, if you are talking about a book it makes sense to have the cover as the image for the article, it's why pretty much all reviews do that.
EDIT: After having been to Ref21 (on mobile) I have seen three images of the the book cover. One from the MoS episode on the book, and two as the images for two articles, both of which were responding to reviews of the book, one of which was mostly about the book cover itself and the "yellow wallpaper" metaphor. All seem rather reasonable to me.
Honestly, it just seems like you're just looking for things to criticize. This is the reason why Aimee and Rachel get "defensive", far more time is spent on speculation about feminist conspiracies and strange criticisms like these than on their actual arguments.
