I don't like the mindset that you "convert" to veganism. It's a dietary choice, and for some, an ethical one.
I think that to equate it with religion would displease not only religious vegans, but irreligious vegans, as well as religious people who view that kind of thinking as a sort of appropriation of patterns of thought that belong to religion, like talking about diet demeans belief, somehow.
The distinctions are only important to those that want to stress divisions in society, usually for some political goal, or for the manipulation of people, either by food-shaming those that feel differently, or by glorifying that which doesn't merit it (oreo and diet coke veganism).
You know what my much better half and I made last night (okay, she did most of it, I only washed dishes and helped with spicing)? A curried peanut butter and sweet potato soup. I could
feed it to any vegan guest that came by. We aren't vegan. My rabbit is a vegan, and some of my favourite meats come from vegans, but I am, most assuredly, an omnivore.
So why did we make a vegan soup for dinner and subsequent lunches? Because it's delicious, because it fit with the mood, and because we had all the components to make it in the pantry and we didn't want to leave the house.
I like the idea that if more omnivores shopped and ate like my much better half and I did, there would be less money going to support factory-farmed meat, and that the money saved might go to buy much better meat, from
local and pasture-raised, grass-fed herbivores, hopefully supporting ideas like the One Bad Day theory of raising animals.
I think we'd have a lot more omnis eating more of their diets directly from plant sources if we weren't constantly told that our chosen diets promote slavery and murder, and that we must be "saved" by the church of veganism, or else be damned.
