It's a question of choice and freedom, MangoSlice. If you don't like "soccer" images just express it by "unliking" them. Personnally there are tons of images i find silly, boring, offending or immoral. I will name none. I already expressed my opinion by unliking. I guess this is how things shoud be. If soccer images broke any kind of rules, the administrators of the site would not allow them to stay here. And as long as they are permitted, I'll keep loading them. Because I happen to love soccer, "boring" as it might seem.
An image does not necessarily have to be funy. Personnally, i don't do -and won't do- nothing but soccer gifs. Yes, soccer can seem boring, and only people who have played it or love it can recognize the beautiful -though rare- moves and touches in a match. A secondes long gif image highlights them better. And, as an answer to the question in the above MEME: BECAUSE IT COMES FROM A SPORTS WEBSITE!
