Earlier quoted context omitted.
Islam is not "dangerous and pervasive".
It certainly seems to be dangerous and pervasive... based on it's history in our world.
If you explore border and internal conflicts around the world today a depressingly large percentage of them list Muslims as combatants, sometimes on both sides. The only recent exception that comes to mind for me is the Russian invasion of Ukraine.
Some of this is just due to the number of followers of the religion. When you have so many people they're bound to be caught up in fighting. But when those fighters use their religion as the casus belli for their conflict it's harder to ignore.
