So you do admit now, that muslims kill to prove superiority. Can it not be proved by intellectual and academic achievements? Look at the Bangladeshi banker (Grameen bank) who won the nobel prize by not resorting to violence (for a change).
All the mullas are combining religion and violence, to such an extent, that in Islam, you can even Rape and kill your own daughter for honour.
Please grow up Rash. It is never too late to become civilized
