I'm a dog lover - but I tend to be frightened of larger dogs.
My parents got a Rottie about a year and half ago (from my brother bc he moved into an apt that would not allow the dog) - I was TERRIFIED.

That dog is the sweetest, kindest, gentlest dog I've ever met. She has the big wiggly butt and soft face. She lays down all the way and squishes herself into the ground so she can be the same "size" as Finlay when they play - she's a treasure.

ETA: I can tell the difference between aggressive behavior and play, though!
