Iker Casillas insults fan on social media.

A fan insulted Iker Casillas on instagram and he replied back. After posting a picture of him and his son at the beach,  a fan asked him to throw his son into the sea and called Casillas a mole. Iker Casillas replied and called the fan a son of a b*itch and tw*t.

Mehn....this is so rude from the fan and I think Iker gave him the best reply. If you are a fan does not mean you can insult a celebrity like that.

What's your take on this?
