I think you are more wrong than right. While 'kosher' is a dietary standard, there are certain conditions that must be met before meat can be considered kosher. These ritual slaughter techniques fall under 'shechita', which traditionally requires that the animal be unharmed (hence unstunned) before its throat is sliced with a knife in a very particular manner. If this is not done, the meat is not eligible to be considered kosher.
Various countries currently have exemptions to their humane slaughter rules explicitly for Jewish and Muslim traditional practices. Here are some citations:
I mean that semantically, not morally. While it's technically true that kosher is a dietary standard, food meets this classification based on the means of slaughter. I have no particularly strong beliefs as to exactly what constitutes the humane treatment of animals.
I run a company selling primarily vegan products (http://screamsorbet.com), but also hunt and fish. I eat less meat than most Americans, but also have two whole wild boar hams currently in brine for Christmas dinner. I care about the conditions of animals, but eat meat with gusto when I do.
I agree wholeheartedly with the parent article that there should a consistent set of laws, and that exemptions based on belief are a loophole that should be closed. Either shechika is humane or it is not; but the religious beliefs of performant should not be a factor.
Then you're being uselessly pedantic, and failing at it - there's no slaughter involved in making quite a lot of kosher food.
"exemptions based on belief are a loophole that should be closed"
Then expand the freedoms of all people to make exemptions on peaceful religious activity superfluous. Otherwise, when dealing with governments that carefully parse and rank claims of rights (particularly when it comes to "weird" minority groups), exemptions can serve to protect particular freedoms for the people who most care for them.
