I'm an ex-ex vegan many times over. I guess I sort of eased into it the hurky-jerky way. Eggs were out by 92 (except in baked goods, like muffins and cake from others, which I consumed for another decade or so). I ate dairy, but I never really cooked with it. I went through long periods where I didn't eat it at all. My cooking was pretty much vegan from the start, but I didn't choose only vegan restaurant and convenience foods (for more than those months long vegan periods) until 2009.
Most of the vegetarians I knew IRL were ethical vegetarians but not vegan. We admired vegans and ate a mostly vegan diets but shied away from full-on veganism for various reasons. The unfortunate "it's easy, you must have a personal flaw" vegan narrative is fairly new. My response is basically the "walk a mile in my shoes" saying. People can't predict how they would react in a hypothetical situation until they are actually IN that situation. No apologies necessary.
