No, the article said that he dyes his hair to attempt to hide from his hertiage. It never said because he is racist.
If anything, the points are closely aligned to Mahmoud Ahmadinejad who comes from a jewish hertiage, yet is famously known for his anti-jewish rants.
In the same vein, he is an immigrant himself, and has tried to dissocciate himself from them, in what the article described as "superdutch" mentality. In the same vien, it is similar practise to Mahmoud Ahmadinejad who tries to paint himself as "superiranian", etc.
