I looked at the Earth Balance container and didn't see any awful chemicals. I compared it to the Smart Balance my DH uses, and the Earth Balance has less ingredients and no strange chemical names. I also looked at the Amy's vegan burger and didn't see any chemicals.
You can go totally vegan and not eat processed foods. If you stick to beans, grains, etc., then you don't have to worry about chemical additives.
Women who behave rarely make history.
