For that reason, I don't think authors should be offended when people don't like their writing. In fact, it doesn't matter if you're a bestseller or a new author, fresh off the presses, there's going to people who connect with your work and others who simply aren't interested. It depends on your choice of topics, your style of writing and as I said in the last paragraph, even their own experiences in life that color how they view the world. And that's ok. You don't have to be for everyone.
It's just a matter of perception.
I've also had people read my books and interpret them very differently than how I had intended. I've had readers miss crucial points and others still who didn't like certain characters. Of course, on the flip side, I've had readers that totally understood and connected with the plot, noticed things that even I had overlooked and had a fascination with specific characters.
Unfortunately, many writers (and artists in general) spend more time focusing on the negative and unpleasant rather than the positive. I guess that's human nature. We zero in on the criticisms and to a point, that's a good thing because it's sometimes a learning curve or a lesson for us. Other times it's irrelevant and not something we should spend any time overthinking.
