I disagree with your premise that veganism is all about thwarting disease by cutting out harmful dietary choices.

I agree that avoidance in an effort to thwart disease may be a valid option.

This has nothing to do with veganism.

Veganism is all about rejecting the commodity status of animals and generally abstaining form activities that commodify animals.

What I consider the root or definition of veganism is my operational definition.

That doesn't mean you aren't wrong.

“Veganism is all about rejecting the commodity status of animals and generally abstaining form activities that commodify animals.”

and why? Because people are a disease in the truest sense to those animals.

> Veganism is all about rejecting the commodity status of animals and generally abstaining form activities that commodify animals.

I strongly disagree. Someone who does not eat animals because they dislike the taste, while not subscribing to "the vegan philosophy", is still vegan.

Even if they wear a lot of fur?

One can wear as much fur, hunt as many animals and club as many baby seals as one wants. A vegan is someone who doesn't eat animals and animal products.

Fair.

Though I’d make a distinction between ‘vegan’ and ‘veganism’.

Sure, I'd still call them dietary vegans.

But not "vegans"?

Dietary vegan, a type of vegan?
