Extremely misleading. The term "Halal" simply signifies that this meat is safe to consume for Muslims and doesn't violate any religious laws.
If you want to go fully into the religious details, both Kosher and Halal meat employ almost exactly the same methods of slaughter. There is no meat sacrifice, no "chanting while watching blood drain". I'm not sure where this post got this from.
I don't see the point of this post. And this is coming from someone living in India where Halal meat has often been a point of conflict.
