Battlefield has started with these flag dog tags and patches with the release of Battlefield 4 and they represent ever single country to kindly not discriminate against anyone. I want you to keep in mind that these two countries are not entirely filled with that type of people, so DICE and Visceral included these tags/patches to not discriminate.
Please create a post on the Battlelog forums about this topic here on the Battlelog Forums about this topic if you feel these flags do need to be removed.
I would also like to add that there are no dog tags or flags of either one of the de facto states so I'm not sure what you meant
