Should sports and Politics mix?

I was going to put a picture of my birthday cakes today(as it's my 20th today getting old!!!!) as I had nothing else to put on until I saw this painting on church at the west end of princess street after reading the metro story about the weekends protest which started a almost hour long conversation on the subject with a friend (based around the title of this photo). Now please I don't want a Discussion on here about the subject only the photo Thanks. I only choose the picture because it was something different and it's an issue right now.
