I read Maeve Binchy too, and don't care who knows it.
I don't think any of us should feel guilty about what we read, just because it isn't always all intelligent and literary.
As said on another thread, a lot of us read for escapism, and there's nothing better than losing yourself in a fictional world for a while - even if it is totally unbelievable with unrealistic characters. It's a chance to escape into another world and forget about your worries - whatever they might be - for a little bit.
