not a very nice product for any Muslim QVC watchers to witness.
You could equally say it's not a very nice product for any Jewish QVC watchers to witness, for the same reasons.
By contrast there are those who are offended by the method of killing animals for meat which is similar under both Halal and Kosher rules. I won't go into it here, but you can do a search in any of the internet search engines.
You could say that meat-based products in general are not very nice for Vegan and Vegetarian QVC watchers to witness, regardless of how the animals are killed.
There are always things in food, beauty, fashion, home furnishing, or other departments, which QVC and other retailers sell which are bound to offend or upset some of their potential customers... and I'm not talking about the sheer ugliness and bad taste of the style of the items.
The decision then is for the customer to decide if they want to shop for the non-offensive (to them) things the retailer sells, or not shop at all on the basis that some products are offensive to them.
It concerns me that we will all end up with our shopping choices drastically curtailed and homogenised into the dullest, narrowest range for fear that someone somewhere will be offended.
By all means provide people with the information to make informed choices, and then let the make their choice. Personally it would offend me more if the choices are taken away from me before I even know what's on offer. It is definitely possible to become too "PC" about things in life.
