One should take no joy or engage in schadenfreude when the factions of the enemy fight each other. They are fighting to be the leaders of the movement to kill the rest of us and they do not weaken their side thereby.Islam has been at war between and among its factions since there was Islam and it has not slowed the advance of that particular Satanism.
You have a good point.
These “purges” actually make them a leaner and meaner opponent. The strongest survive and bring their accumulated knowledge and hatred straight at us.
Interesting times ahead.
