I see a lot of people at least joking about going vegan lately. I’ve been vegan for roughly… ah, I want to say 4 years now? I lost track awhile ago. It was around the time the wreckers came to Hexbear and convinced a bunch of us to watch Dominion (highly recommend doing so btw, it’s free online).
ANYWAYS, if you’re interested in more than just shitposts and are seriously interested in veganism I was thinking I could help answer any questions you have. Comment here or send me a DM if you’re blush shy. 
This comm has limits on what we can talk about btw, such as diet. And I think the whole website has restrictions on recommending specific brands of food? So DM for questions like that, thanks.
Most grocery stores sell vegan butter products, at least in my neck of the woods. Sometimes they are advertised as vegetable spread, sometimes they directly say vegan butter. But regardless of brand they exist and imo are very similar to animal butter in taste and texture
This very much depends on where you live. Never seen vegan butter in my city but there are homemade vegan butter recipes, generally using soy milk, coconut oil(naturally saturated) and some other things like emulsifiers.
Edit: Apparently this is not the comm for recipes sorry.
They may not be especially well-marked, but you can often find them among other margarines.
I live in a third world country where plant milks just recently got into normal markets.
Even the catalogue for the local vegan shop doesn’t have any butters.
