Strong demand refers to demand for halal meat, not demand that they remove anything. The article you reference is a rehash of a sensationalist Daily Mail article. The orginal article is even linked at the bottom. That article distorted a PR release by subway talking about customer demand for one type of product, and presented it as something else. The demand for halal meat was actually in opposition to animal rights groups who campaigned against halal meet because they don't agree with the way the animals are slaughtered. This story is actually a counter to your point in that respect. The problem is that the Daily Mail took something akin to McDonalds serving biscuits in some places and english muffins in others, and turned it into a "Muslims are taking over" scare piece. There is a better example of your original point. McDonald's stopped carrying halal meat in the US after a lawsuit by animal rights groups.
