Shoot you down? F*CK YOU! how about I just behead you?
And there is a hadith that says "Wala yadkholana al janat ayato thayad" it means ,how to say this, anyone who lacks of honor will NOT enter Heaven,in a sense it justifies these barbarians' acts, I was taught this over and over when I was kid in schools,and till now it is widely taught.
And if you forgot already ,Most Muslim take the hadiths more seriously than the Quran.
So do not try to mess about ,and bugger off until you got a real comeback that justifies the beheading or throwing acid.
And yeah, I won't talk about other religions because I don't have a personal experience with any other than Islam.
You got two choices, accept the truth that innocent people are dying by the day, or just bugger off and come back with something that makes sense.
