“Radical diseases require radical cures.”
Islam is a societal cancer.
Genetically, cancer cells are only slightly different from the cells of the host, but those differences create behaviors that make it impossible to coexist. While not every cancer cell is currently engaged in invading and destroying vital organs, they all can go that route at any time. Therefore the goal of therapy is early detection, and complete eradication of every cell through aggressive therapies.
The same thinking will have to be applied to Islam, I’m afraid. And the same basic treatments: radiation, chemotherapy, and surgery.
Until some kind of vaccination is available, surgery seems to be the only effective solution.
