People....and Hort.....turkey bacon is not bacon! Where are the turkey pigs?!?:p
bacon is bacon due to the type of meat/slice, which generally are thin strips of meat along the pigs underside, you can get the same type of material from a chicken/turkey (though it tends to fall apart, thus they proccess it and reform it into bacon)
kinda like how you have "pork chops" and "lamb chops" 2 different animals, same piece of meat...
kinda like aswell how you can make moose bacon =D yum yum moose bacon!
