You got to be living in a cave to not know that these gestures (even though made in humor) offends every ethnics pertain to them. How would you like it if a group of people stretch out their ears while taking a picture like this Spanish players; thinking that is portraiting a positive image to the your host country, if your ethnic's physical trait happens to have Dumbo ears (not that I am saying you do)?

Should I then ask the photographer or the company sponsering this what the gesture means?
It is the lack of knowledge and understandings of the outside world that you and these Spanish basketball players seems to hold.
