Sheena shouldn't get that much of a reaction because she's mostly human. A very pretty human, but human nonetheless. Her tails and ears can be thought of as fashion accessories, people do dress funny sometimes.<br/><br/>I also don't think giants are as common as you make them out to be. Now at 6 something Rairaku is tall, but not really giant.<br/><br/>But don't downplay the reaction to a Devil Fruit. Those things are supposed to be incredibly rare. Perhaps they feel a little less so because they often appear in the paper, but not so much face to face, and even then you're looking at someone with supernatural powers. If someone has a fruit power then he's a big deal by default, and you pray it's not someone who will level your town on a whim.
