I'm both unsurprised and deeply exasperated with your family, to find out that they're not respecting your dietary choices. But then, I also wouldn't be surprised to hear about them "accidentally" exposing someone to a food allergen that they'd been warned about, and claiming that they thought it wasn't that serious or that the person was faking it. So there's that. (Also, I suspect it's probably easier to keep kosher with a vegetarian diet. I'm not sure if there's actually hella amounts of pork in the grocery stores these days, or if I'm just noticing it more and not having any luck finding sandwich meat that isn't pork and also isn't turkey or chicken.) But the thing is, you're allowed to make choices about what you eat and how you interact with the world! You're allowed to go "hey, y'know what? I really don't like how the industry treats animals right now, and I'd rather only consume animal products that I know were ethically obtained, and I currently am not in a situation where I can raise my own animals so I won't eat any meat at all". There's nothing wrong with making that choice (and I think it's a pretty hard one to make, too). I might have questions about cutting eggs and dairy out of your diet, but I would not for a second think it's my place to try and tell you not to do it if you feel it's the right choice for you.
