Indeed. People do the best they can. I agree with the above that
being vegan doesn't mean you have be anal retentive. Oprah had an episode on where she had spoken of being 'veganist': people eat primarily vegan, but do consume dairy once in a while...
in a perfect world, it'd be easy to be a vegan purist. I wouldn't miss icecream, etc if the vegan versions were as inexpensive as the dairy. It's all about marketing, most vegan items being a niche market... In the future, though, I bet nearly everything would be vegan. It'd have to be to sustain the planet, that's for sure...
