Personally, I think the article on Book Riot hones in on what the article writer objects to and got offended by, leaving out some of the main points of the article in the first place --- but that the original article does end up in a bizarre, almost finger-pointing line. Ironically "We Have to Save Books from the Book People" seems to in its way warn against a type of eliticism that can exclude certain books or tropes, but then seems to want to grow a line between "readers" and "book people", mocking and minimizing the latter.
To believe in this is to assume "book people" in the definition given cannot actually be true, legit readers in comparison to an "actual reader". This is something I find strange, as you'd think being a reader and lover of books can transform some into "book people" when they meet the book world on social media platforms and want to delve into that further - BookTube, BookTwitter, BookTok, Blogs, Goodreads reviews as mentioned, Pictures of books on instagram. I'm certainly not assuming that means they're not 'serious readers'.
I proudly self-identify as both as "reader" and "book people" from these definitions. I haven't been one who makes a bookish Christmas tree, but I'll admit I've been slightly tempted
Hell, this weekend I'm participating for the third year in a row in the #24in48 weekend read-a-thon, challenges on Twitter and Goodreads, my Instagram feed is mainly books, etc., etc.
I'm also curious on mentioning e-books and audiobooks in some of these examples. Curious on others thoughts on both articles.
