Make no mistake about it. If I were a Muslim, VenomFangX would be dead, so it didn't surprise me to learn that Muslims have threatened his family. I'm actually surprised that Muslims waited so long to resort to such measures.
But I'm not a Muslim, and I believe that resorting to violence and threats is wrong. This is why I find the following video disheartening.
NOTE: I have to question VenomFangX's claim that he never meant to offend anyone's beliefs. The following videos will show what I mean. (For those who are wondering, I'm posting these videos, not because I approve of the tactics, but because free speech is being threatened and because people need to understand why VenomFangX and his family are being threatened. I saw these videos a long time ago. I never posted them because I would rather approach Muslims in a manner more conducive to discussion. With that said, the material VFX presents is quite accurate, and he certainly has the right to get his point across without his family being slaughtered.)

It's clear from these videos that VenomFangX did intend to insult Islam. Indeed, the reason that he was threatened is obviously that he is extremely talented at ridiculing the beliefs of his opponents.
