Barbaric culture didn't create it. Islam created the barbaric culture. It was a counter culture to pagan Arabia of those times where freedom of speech was widespread which is evident by the number of poets during the times of Islam's birth. However, Muhammad ordered execution of many prominent poets who used the contemporary culture of criticism through poetry. A few notable casualties were Abu Afak, Asma Binte Marwan and Abdullah bin Khatal etc. Furthermore, Jews and Christians lived peacefully with Pagans back then. Muslims started killing or converting all other people by making lame excuses and brought the pluralistic society to an end.
Hail Apostasy!
