That's quite a straw man you've weaved there.

First, nobody said anything about eating only meat as a diet. I'd wager zero people do that - you would quickly develop vitamin deficiencies and ultimately fall ill and die.

Secondly, you've moved the goal posts to vegetarianism, which is not veganism.

Third, just because a vegetarian diet can be sustainable (in the sense you won't fall ill) doesn't mean it's the natural diet for a human. It's not... Your teeth and many other parts of your human body tell us differently.

Fourth, there are several cultures on this planet that strongly favor vegetarianism, but none are strictly vegan and few are strictly vegetarian. As already pointed out, vegans often have to take supplements to remain healthy. That's biology telling you that diet isn't natural.

Lastly, deciding to be a vegan because you believe current agriculture practices are harmful to the environment is a choice based off your beliefs and therefore is an ideology. That was the original assertion.

You seem to be conflating carnism for the carnivore diet. Info on what carnism is can be found here [0]. There's a lot of good stuff in that article, I think! Unfortunately, there are people who are indulging in a pure carnivore diet. You're right that it's patently unhealthy, and frankly it's a little weird.

Veganism is a subset of vegetarianism. I'm trying to be flexible with my position to allow for good discussion - being either vegetarian or vegan is typically healthier and objectively better for the environment [4].

Recognizing that humans are omnivores also means that by definition we can sustain ourselves solely by plant or animal matter [1]. Your statement of "Making a conscious decision to go against biology [...]" is plainly inaccurate, as we are quite capable of living healthy lives without meat.

There is plenty of evidence to support the fact that animal agriculture is harmful to the environment [2][3]. In fact, it is the second largest contributor of green house gasses.

I get the sense that there is some frustration coming through in your thoughts. Please keep in mind this is exactly how cognitive dissonance expresses itself. Take a breath, check out some of the citations below, and try to think about this data with an objective approach.
