Racist abuse on the pitch is racist abuse in real life. Racist abuse to one man is racist abuse for public consumption. If you make it easy for someone who shows no regret, don't be surprised when he does it again, and don't be surprised if people hold you partly responsible for enabling it. Suarez is a proud man, and it's worth remembering in everything that is written about him what exactly he is proud of.
France's equivalent of our Supreme Court banned the French comedian, Dieudonne, from performing his roadshow in Nantes on the grounds that it represented a "serious risk" to French "values and principles, notably human dignity". This begs a big question about what the FA is doing about Nicolas Anelka...
Let me say once and for all that until we tackle the issue of racism in mainstream society, we cannot get rid of it in any other part of society - of which football is but one of many... Until we see all black people in the same way as we see our black partners, friends, this unconscious racism will continue. There are degrees of racism, and we convince ourselves we have no tendencies, because we would never do or say what John Terry said, or Luis Suarez, or CSKA Moscow, but the majority are (me included) somewhere in between that and Mother Teresa, but we have to acknowledge and accept it.
The fact of the matter is, rightly or wrongly, footballers and top sportsmen enjoy very little privacy, opinions on this will vary drastically. Nowadays, it comes with the job and lifestyle that your private life as a star football player is in the public interest, so you could argue that if you don't want your privacy infringed upon, don't become a pro footballer.
