We can go back and forth on this so I'll leave you with this, according to the economist: "According to Arab Barometer, a pollster, much of the region is growing less religious. Voters who backed Islamists after the upheaval of the Arab spring in 2011 have grown disillusioned with their performance and changed their minds. In Egypt support for imposing sharia (Islamic law) fell from 84% in 2011 to 34% in 2016. Egyptians are praying less, too (see chart). In places such as Lebanon and Morocco only half as many Muslims listen to recitals of the Koran today, compared with 2011. Gender equality in education and the workplace, long hindered by Muslim tradition, is widely accepted. “Society is driving change,” says Michael Robbins, an American who heads Barometer"
Yes Egyptian culture is home to regressive cultural views especialy on the idea of non-belief but to say they are complicit to terror is complete non-sense.
