I'm pretty certain that everything is not art... And I was actually complimenting the photo. And when I comment on something it's most likely my point of view I'm expressing.(which is the "opinion and taste" you were on about)
I know you're complimenting the photo. It's cool. When I say everything is art I mean we can't judge what is and what isn't art based on our ideals (opinion and taste). A six year old's drawing of dad is just as much art as Da Vinci's Mona Lisa. Whether it's good or it sucks, offensive or acceptable doesn't matter. It is what it is, art is art.
