I judge people by their lack of library, not what's in their library. 46% of Americans didn't bother to read a book last year. I personally find that ridiculous.

I will also say that if they only have religious books, I don't think that counts either. But aside from that, doesn't matter if it's highbrow or lowbrow, isekai or scifi, as long as they read SOMETHING. Besides, some of the stuff I read is trashy so who am I to judge.
