Hate Graffiti in Jaffa

As we are nearing the municipal elections, hateful graffiti against Jaffa's Palestinian population has started sprouting up at different locations all around.
From "Kahana was right" through "Death to the Arabs" and "F* Islam" to "Arabs Should not be allowed to Vote" sprayed on walls of homes and public buildings in Ajami, Jabaliya ("Givat Aliyah", as it is called by some) and central Jaffa.
I feel like buying a can of white paint and wiping it out and hope Jaffa's Palestinian population will come to vote for change. A complaint has been filed at the police.
As this happens in the same week Barack Obama is elected as the next president of the USA, it seems all the more symbolic.

For those Hebrew challenged: the graffiti reads "Kahana was Right" .
