Why can't He come?? Don't you trust your Allah that He even exists or not?
Or you think you guys are holy warriors sent by Him to save Allah's respect???
OH Man. You totally screwed this. it was meant to be a "light joke". but as you have took it so hard, so now i have to answer you in the same Mode.
You have actually asked 3 Questions.
1. Why can't he come ??
Ans: because he have other works too. aap kay lye khaali nahe beta God.
. man ! i can't help this.
2. Don't you trust Allah that he even exists or not ?
Ans: I trust Allah and i do agree that he exist. it was not even the Point behind "Don't expect him to come on TV and defend himself". it's My believe, keep it to me.
3. Holy warrior's send by Allah to save his "respect" ?
Ans: A Person saying i wan't to save Allah from disrespectful words is the major disrespect in my Opinion. Ab Allah ko Apnay aap ko bachane kay lye hamare madad darkar hoge ? it's a Joke man.
But, Here the Point is not to "Save Allah". But to make other's respect "our believes". Man You can refuse to agree with His existence. You can refuse to witness that HOLY PROPHET P.B.U.H is the Last messenger and Prophet of Allah. But You are not allowed to disrespect him by making his sketches, making cartoons of him, making abusive YouTube videos against him etc etc etc.
So In-short, Blasphemy is not about "refusing to believe", it's about "respecting our believes".
I respect Your Krishna, I respect Your religion, You should respect my religion, Muhammad P.B.U.H and Allah. and blasphemy is not only related to ISLAM. see the previous Posts in this thread and you will find that even Muslims are accused for blasphemy against other religions. In such a case petitioned in Court. Sikh community accused 6 Muslims for disrespecting their turban. Go through Post # 23 for Clear picture of all this.
