It goes beyond just illicit drugs.

Vegans want to live on chemistry alone.

Think about it, what is beyond veganism?

You've cut so much out of your diet and now plants are all that's left.

What does someone who wants to stop eating ALL living things do?

They start eating minerals and chemicals only.

Isn't that Bill Gates' dream for us? That we end up eating cultured flesh sponge patties filled with chemicals?

Vegans, to them, are "pure" life forms that no longer subsist by eating living things. Just watch, soon they will up the ante and there will be those who live only on supplements derived in a laboratory.

Ultimately, they do want for us to live in pods with tubes feeding us raw nutrients synthesized in a laboratory, just like the red goop pods in the Matrix.

Veganism is prepping for that narrative shift. It's a foot in the door to have us concede our diets to them and be whole-ly reliant on a chemical based diet, with Big Pharma in charge.

Heading back to symbols though, and I think vegans being those who seek to "purify" themselves by eating a completely controlled diet, able to order a chart of every single chemical in their body, is the likely reality. They are the type who are obsessively clean, like Monk, and would love nothing more than to turn themselves into machines such that they can eliminate any and all mystery in the construction of their bodies. In other words, they are so meticulously insane when it comes to health that they are even willing to cast aside their humanity because they find it filthy.
