There is something about a person who looks back at their own actions, concludes they were unacceptable, and accepts the consequences with genuine remorse.
However, in my book it's different to someone who broadcasts the encouragement of a hate crime, puts their name to it, and waits for others to shame them into apologising for fear it will impact their earning potential, showing no remorse.
But that again is different to someone on one forum being sympathetic, and another publishing abhorrent content in direct contradiction to the first, where they have a different "persona". And when being exposed, denying it, weaselling out until evidence is provided.
Repeated homophobic tweets are like repeated racist tweets, and are like repeated sexist tweets. They do deserve a 9 game ban like Suarez received for being racist.
I don't think it will change grays attitude in the slightest, it would take perhaps education that is beyond his ability, but the ban would show everyone how unacceptable homophobia is in football. I don't think the fa do anywhere near enough, which us why there are no openly gay pl players.
