Sports Illustrated, like other magazines, wants to sell as many magazines and gain as many online viewers as possible. To do this they cater to the most common denominator when it comes to women. The majority of men do not find tattoos attractive and so it is removed from the images.
The reason this works well is because even the men that do like tattoos probably won't know it is missing and therefore Sports Illustrated really has nothing to lose by removing it and has something to gain by doing so. I am also including an image for future answerers because the one in the question is from a site that does not allow hotlinking.
Most likely because association with the word "tramp" has a fairly negative connotation! That being said, she's still (one of) the best looking race car drivers out there.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
