The best what one could attain in this world is the Mercy & Pleasure of Allah for the hereafter. This can only be attained when one surrenders to the will of Allah without any doubt peacefully (Islam). The will of Allah is totally clear from the Noble Quran & further the guidance from the prophet Muhammad (p&buh) in Hadidth (teaching/guidance) and the noble Seerah (his life). (p&buh)
It is clear from the Noble Quran, which the prophet Muhammad (p&buh) is sent to us as a blessing for the mankind and NOT the Muslims only. So if The Creator states that in his final book the Noble Quran that the prophet Muhammad (p&buh) is a blessing to mankind (21:107) and someone performs an act of disrespects to him (p&buh), this is a serious offense and the believers are well guided from the teaching and history of WHAT the responsive action should be. The history also clarifies the fate of those who did some similar acts during his (p&buh) lifetime.
Every believer has a role in his/her life and within that it is his/her duty to show and share the responsibility one has being the believer. [Surat Al Asr (The Time 103:01-03)]
Likewise the non believers are also having an individual role within the respective lives, especially when they are blessed to be among the believers and further when the believers are here to share the wealth of the beautiful code of life, THE ISLAM
After all this, there is no compulsion at all to believe in the words of Allah (SWT), The Noble Quran and or the teachings and the life of the blessed prophet Muhammad (p&buh) and or the word of advice from the people among us (Warner). Eventually all of us have to be accountable to each and every action done in this life.
This thread proved to be a filter to screen out the 'real believers' and the 'still to be the real believers' and further also exposed a lot about what has been hidden in the hearts of the non believers, I would say due to limited or no knowledge.
Great efforts have been done by the believers to clarify the position on this situation, May Allah continue to reward you for the fear you carry for Him.
May Allah give more guidance to the 'still to be true believers' BEFORE time & May Allah also soften the hearts of the non believers so that they get a chance of sincere repentance and leave this world on Haq (truth).

Allah knows the Best.
