On Thursday, the Twitter account for the Waterstones bookshop in Uxbridge, West London, decided to talk about men who refuse to read books by women authors.
And said those men are of "a certain age".
And while some loved the tweet, obviously some men got pretty mad.
After the backlash, the bookshop added a tweet to the thread to say this doesn't apply to *all* men.
BuzzFeed News has reached out to Waterstones for comment.
