Greetings and peace be with you fromelsewhere;
The "inhumane Satanic system" are the terrorists who blow up innocents in the name of their religion.
When atheists kill other atheists, it would be silly to put the cause down as their lack of belief. They kill because they are angry about something or someone.
What is making these terrorists so angry, that they will kill? Are you really still blaming Islam?
In the spirit of praying for justice and peace for all people.
Eric
