I think you're confusing the idea of ethical eating and veganism. There is certainly a cross over, but a vegan will choose the products they consume (including toiletries and clothes as well as food) based on if this is an animal product, ie is it directly made by an animal eg meat, fish, eggs, honey, leather, some cosmetics. Eating ethically means coming to your own judgement on which products cause the least damage to the environment, so this may include eggs from your own chickens for example, locally grown veg, trying to avoid 12p bananas that have flown halfway around the globe, soy products etc.
I was vegan for a few years, now I don't really identify as anything. I made the choice that putting a label on what I was was putting pressure on every meal, and I didn't want that, so now I make decisions on my purchases based on what I feel is right, that does mean that I still largely eat plant based, I avoid soy and palm oil, but I also consider factors such as food miles and the nutritional benefit of a choice - things are getting a lot better in the last few years but I was quite unwell as a vegan as I eat out a lot/travel and there are only so many plates of chips/crisps and an apple that can sub in for a meal on the go before your body starts to rebel. I look at it that any small change I can make is beneficial for the environment, less food miles, less processing, less plastics, but if I make a choice every now and again that involves a bar of Galaxy then I that's a choice I'm happy with and it doesn't define my whole existence.
