LOL ok. "We need to kill you all" edgy as hell, but it's ok, as someone as idiot like yourself, I don't even take that as an 'insult'. Western Civilization will kill itself eventually.
1: Yes, every religion believed itself so, just like every political, philosophical, and scientific ideologies thought they were the "true" systems. "Those that refused" was it 'those' or the 'society' ?
2: "when over and over again imams and scholars decry all technological or cultural advancement" Wrong. This is not Christian Monasticism, This is basic Islamic Theology. Basic Islamic Assets like Compasses to know where to pray, or Engineers and Architects to build Mosques is enough to prove that Islam is just as much physical as it is spiritual. Scholars will most likely want to prohibit haram technology , "Sexual Desire" mechanics, "sex toys" , "Illegal Adultery" etc.
3: "when over and over again all culture is spat upon by your imams"
Definition of culture
1a : the customary beliefs, social forms, and material traits of a racial, religious, or social group; also : the characteristic features of everyday existence (such as diversions or a way of life) shared by people in a place or time
As per-definition, Islam Allows All Cultures and Traditions. Even the Prophet (saaws) Wore Traditional Arab Clothes etc. Islam Only forbids Haram things in Culture . 'Painting' is not haram. Drawing Lively things (heads i.e nose, mouth, eyes etc.) is. Drawing Non-living things is not. As Per-Salafi, Sculpting 3-D Statues is Haram. Music Is Haram. Telling Stories is definitely not haram (IDEK from where you got that). Plus, by 'Cultural Benefits', I mean Balancing-out the Haram From the Halal in cultures.
4: I never stated so.
5:
“Verily, you (O Muhammad) guide not whom you like, but Allah guides whom He wills. And He knows best those who are the guided.”
