I'd want to wear gloves picking up the pieces, but I thought that was fairly routine practice anyway.
Just think of those Muslims who've acquired AIDS in a sinful way and think they're going to hell for it - but kill yourself and some infidels - instant Paradise!
Or someone who's become infected innocently, some wife, who is shunned and condemned and wants to redeem the family honor...
Dengue fever now - when you see a Muslim who looks like he's at death's door, wearing a backpack, and being wheeled onto the subway on a stretcher - you might want to wait for the next train.
I was thinking the same thing, but that's pretty much only in the American context. There are plenty of North Africans carrying around all kinds of nasty diseases, and AIDS is quite prevalent among heterosexuals in Africa.
