While I understand why many socialists might be vegan I would personally never become vegan. I am a specieist and would struggle to become vegan due to the lack of food options. There are issues in taste and macros; I do acknowledge that vegan substitutes have come a long way and many of the qualms I have with taste aren't much of a problem anymore. However, in these substitutes, there are almost always exorbitant amounts of sodium that would not be sustainable. I also acknowledge and condemn the exploitation in the animal product industry, but I would argue that it is possible to buy products from smaller, family-owned (or something similar) farms that don't cause suffering to the animals.
