**I am of the opinion that Christians should NOT consume ANYTHING that is halal but especially halal meats.**
Ask no questions but for conscience sake. However, if the person selling the meat declares “This is Halal!” then back away and don’t eat. To do so makes you appear to support moslem nonsense.
On the other hand, I have no problems with Kosher products.
Or, you could bless it in the name of God and make the sign of the cross, over the meat, right in front of them.
