All margarines and buttery spreads are refined products. You're not going to the store to gather up ingredients and making it at home unless you have a pretty good chem lab. Veganism has pretty much devolved into being every bit as processed as the rest of corporate produced food.
Bollocks. If you want to eat shit, vegan or otherwise, you can. There has ALWAYS, however, been loads of vegan foods in supermarkets and elsewhere that are fresh, or canned, untainted by the crap some companies put into them. Plenty of folk don't bother with the processed shite you say they do.
