Yeah, that's one way to understand it (though I wouldn't call this impressionism). At the most human level, I'd say if someone connects with it, it's art. I did connect with these pieces so was bummed to see someone insulting them -- and an artist, no less.

But it's hard to say why ... and that's where I can start to ask why and start engaging with the work.
