why so many young Muslims appear to ignore the spirit of the Qur'an and the historical context in which Islam was founded
They aren't ignoring the spirit or historical context of its founding. They are attempting to emulate those early Islamic marauders.

Islam was forward thinking in its treatment of women and attitudes to women working and owning property This is also another assertion that is without any corroboration.
We only have muslim say so regarding the poor treatment of pre-Islamic Arabian women. Yet Muhammed's first wife was a successful and wealthy business woman before Islam was even conceived. There were powerful Arabian queens such as Zenobia who led a revolt against the Romans.
Pre-Islamic Arabia also had female goddesses including the daughters of the moon god Allah (yes Allah was a moon god before he became the Allah) - Goddess Al-Lat, Goddess Al-Uzza, and Goddess Manat.
Robert Hoyland, an Oxford Historian, has a book 'Arabia and the Arabs from the Bronze Age to the Coming of Islam' which has a section on various pre-Islamic Arabian tribes. He found:
- evidence of matrilineal tribes, where lineage was determined through women. Children were regarded as belonging to their mothers, and not a male progenitor.
-Women had the right to easily divorce their husbands such that their husbands had to leave the homes, and not the women.
-Women were able to marry multiple men
- women could contract men in temporary marriage for the sake of producing offspring
- women could work and did so in roles outside the home such as public administrative officers
- women could maintain considerable financial independence
Islam has done a great job at whitewashing and re-writing history to present itself in a favourable light and too many seem to just take it's word for it.
