Mohamed Cheikh Ould Mkhaitir
According to Abdel Nasser Beibe, a Mauritanian activist and representative of the Arab Thinking Foundation, there are many people who wrote about the same things as Mohamed, but they belong to the white community, who are the majority of the people, and no one asks for their death.  Their tribes and their families defend them against any attack.  But Mohamed comes from the "blacksmith" minority, and are very marginalized.  After the article, his family and caste had to deny him, and his parents had to go into exile in France.
