I am not defending Chris Brown, but I find there to be a gross double standard.
Glen Campbell got a tribute this year at the Grammys even though he repeatedly beat his girlfriend, on one occasion knocking out her teeth.
Paul McCarthy is still held as a national treasure even after he stabbed his wife.
John Lennon is still held as an idol of peace and love when his son goes on about the domestic violence he and his mother suffered.
Jonathan Rhys Meyers is still loved after being abusive to women in public and beating his much younger girlfriend.
Charlie Sheen is still a praised after being exceedingly violent to his partner.
No one questioned Sean Penn's rehabilitation after he tied Madonna (his then wife) to a chair and beat her with a bat. No one says people should stop working with him. No one wondered why Madonna still cared for him afterwards.
I could go on with so many more examples but the point is clear - these men can be forgiven for what they did and Chris Brown isn't. Why do they get to get away with it? What is different about Chris Brown? It's not lack of remorse (Sheen and Rhys have been very unremorseful, Sheen bragged about it, and I don't know of any to give a public apology about it), it's not society getting better (they are all still in work), what could it be....
And the tattoo is a DÃa de los Muertos tattoo. Potentially culturally insensitive, as was his recent Halloween costume, but unrelated.
