Treat Islamic Radicalism as a disease like ebola it is a contagious mental illness.

Treat islamic extremism as an infectious disease. What if we treated it as a pathogen, it makes for an interesting discussion on mental illness that spreads by air & the internet. We have computer & internet viruses, biological viruses and if diagnosed psychological viruses.
If radical islam were a pathogen like ebola a quarantine from infected countries would be simple and acceptable. I think we should treat radical islam like a pathogen because in many ways it is a lethal illness. If 50 Americans died from ebola coming out of Liberia a ban on Liberians entering the country would be logical and widely accepted. I think the conversation should be framed in a medical sense because radical islamists are mentally ill and highly contagious.
