I've been vegan for 15 years, and I've been eating meat the entire time. I've also been drinking milk and baking with butter.
Not mock meat. Not fake butter. Not imitation milk.
I eat real food based on real ingredients. I don't consume substitutes, alternatives, analogs or replacements.
I grew up conditioned to believe that animal-based meat, dairy and eggs are the barometers by which all other comestibles should be measured. Thus, we're told, anything that doesn't come off of or out of an animal is considered an alternative.
The marketing arms of the meat, dairy and egg industries have no doubt shaped our thinking in this area. The National Milk Producers Federation has been trying for years to forbid plant-based milk companies from using the word "milk" claiming they have proprietary ownership of that word. Try telling a lactating mother she has to say breast beverage.
