WHY HAVE implies that its a thing of the past...which we both know is not correct. WHY DO conveys that its still happening and will keep happening. 100+ people died in Peshawar a few days ago....
;) Gotcha ??
You can't say why DO, 'cos only a HAND FULL of those so called Muslims do what they do, so we say after the incident has occurred, why HAVE they done that.
Understood?
U say as if this kinda act is just glued to us, and NO OTHER religion follower does anything as such. Hence no justification.
Gotcha?
