Damn, that is a brilliant idea there Rich!
I bet if you make a website something along the lines of
this type of layout, it would be a huge traffic generator and possibly draw advertising interest and supplemental income!
Call it "Islamic Crimes Against Humanity" or something truthful and forceful like that. List total murders and sub-categories for beheadings, suicide bombings, shootings, hangings, stonings etc...list total crimes against women-rapes, stonings, genital mutilations, forced arranged marriages, divorce by murder...list crimes against children - exploitation, rape, incest...crimes against livestock...
You don't even have to be 100% accurate in the tally, since starting historically you would have to go with estimates anyway, and once some initial stats and assumptions have been made run some run rates and extrapolate to current populations as well as update for larger scale real events like these 141 people. It's like building a budget off forecast. Wouldn't be that hard.
I say you gotta run with this idea Rich!
