I'm in a very similar position to you right now. I've been calling myself vegan for a few months now (though it was about a year ago that I switched to an almost entirely plant-based diet), and I'm already starting to think about switching to calling myself a vegetarian, while still continuing to eat an almost completely plant-based diet. For me personally I feel like it would work the best to be completely vegan when I'm cooking for myself at home, mostly vegan when I go out to eat but not needing to religiously check the ingredients of everything I order, and not holding myself to any standards beyond mere vegetarianism when I'm at social/professional events or a guest in someone else's home. I have found that it can be quite difficult to be completely vegan in a lot of social and professional contexts, and I feel like it can sometimes impede relationships. I really don't like feeling as though I'm burdening people or rejecting their hospitality, and I've already felt that way a lot trying to be vegan.
Besides what's best for me and the people around me, I also feel like it isn't necessarily better for the cause of animal rights/welfare to be 100% vegan all the time. I think this is a really complicated topic that probably depends a lot on the specific social context you're in and even the specific people you're with, but honestly I think in at least some scenarios some people might be more open to the idea of a plant-based diet if this person they know who's on a plant-based diet is more flexible and not rigid about it. That might make the idea of a plant-based diet seem less daunting and more doable to them. I think a lot of people write off vegans immediately because the diet seems so hard as to be impossible to them, particularly in the situations that are making me consider dropping the "vegan" label myself. So they don't pay any attention to what plant-based dieters have to say because it seems too extreme to them. That drives people away from the cause.
This relates to another opinion of mine that there seems to be a really harmful vegan versus non-vegan dichotomy in the mainstream vegan movement. In this philosophy, it is morally required to completely refrain from the use of animal products at all times (unless there is some very good reason not to, a reason that would have to extend far beyond personal convenience), and you are simply not living up to your moral obligations if you are not doing this (and that includes frequent meat-eaters, vegetarians, flexitarians/reducitarians, and even people who are mostly vegan but make exceptions sometimes). I honestly don't think this is helpful for the animal rights/welfare movement. I think it makes a lot more sense for the movement to be welcoming to anyone who cares about the issue and wants to do something to reduce the harm they are doing to animals. Yes, of course the fewer animal products you consume the better, and it's awesome if you're consuming little to none, but I think it's really dangerous to set up a binary between "people who never ever ever consume animal products" and "literally everyone else", and to paint the latter group as completely awful people.
The thing is, I don't see any special reason why completely abstaining from animal products at all times is morally obligatory. There are lots of other kinds of consumption habits that cause harm in some way (eg. things that are not environmentally friendly or sustainable, things bought from companies that mistreat their workers, etc.), and I very rarely if ever see people being absolutist about that. When it comes to those things, people sort of seem to adopt an attitude of "try your best" -- you know, reduce your waste, recycle when you can, try to buy secondhand, maybe buy fair-trade, etc. -- rather than vilifying people who are really trying to reduce their harm but aren't doing so 100%. Because, the thing is, it's impossible to cause absolutely no harm through your consumption habits! Maybe it's possible to be completely vegan or only buy fair-trade or be zero-waste and so on and so forth, but it literally is not possible to cause absolutely no harm through your consumption habits. So I honestly do not see the logic in saying that it is morally obligatory to be completely vegan based on the premise that it is morally obligatory to cause no harm at all to animals through your consumption habits. Since I think it's impossible to cause no harm whatsoever, I try to do the best I can across all areas of consumption, rather than picking one specific area and becoming absolutist about it.
Anyway, thanks for the post; I'm glad I'm not the only one who feels this way.
