I went to www.barnesandnoble.com and searched for “dangerous” - and was pleasantly surprised with the top results - lots of Milo, Levin and Breitbart:

That said, my experiences at their brick & mortar stores is that they are a bunch of uber-Lefties, and I generally don’t buy from them.
I do think that it’d be funny as Hell if 100,000 of us searched for “Dangerous” on their website, and then didn’t buy anything...it’d certainly send a message.
My guess is that B&N doesn’t want conservative books in their physical stores, because their ultra-Lefty clientele would get triggered and leave the store in a huff because they saw the cover.
Or maybe their just recognize that their Leftist customers are likely to quietly damage the books in the store, as a form of “protest”, and don’t want the expense.
