Why do people on here hate lower back tattoos so much?

There are only so many places on the human body, and having a lower back tattoo is a nice, large surface area that is both accentuated when tattooed and also easy to hide... you can have a mive tattoo there but still keep it discreet if you want to. Why are people so quick to brand someone a slut/wannabe if they have one? It's about as unoriginal as anywhere else on the body (apart from perhaps the face and even then) because you can guarantee that no matter where you get tattooed, there are probably thousands dotted around the planet with a tattoo in the exact same place.
