That is pure bullshit and a Salafi propaganda!
Sufis visit the graves of pious people because they are the gardens of heaven and earth. Sufis wear turbans because the prophets and angels always wore them. Sufis praise Prophet Muhammed (PBUH) because Allah and the angels always praise him and his name "Muhammed" means the praised one.
On top of that, Sufism is part of Ahlu Sunnah Wal Jama'ah. They are the real Muslims, forget those Asian ones that hijacked Sufism.
Some of the greatest Somali scholars were Sufis even during the medieval and early modern periods. I can list them for you. Even the greatest Somalis like Sayid Abdullah Muhammed, Nur Ahmed Aman, Haji Sudi, Abdirahman bin Ahmad al-Zayla`i and Uways al-Barawi were all Sufis.
Now I'm not Sufi because I follow Shafi'i, but I consider Sufis as real Muslims.
