ADVICE! Parents mock me to the point I don't want to speak to them.

Hi there,Background, I (26f) have been vegetarian for...5.5 years? I'm transitioning to vegan slowly (damn chocolate!) and I'm super low key about it. I don't really mention it unless I need to give a heads up about a meal or something or if I find a new recipe. I don't like talking about it very much as in my experience, the best way to get folk to be easy about it is to not lecture and stuff and just show how good the food can be! Everyone I know is really nice about it, supportive etc and don't bat an eye.My parents on the other hand are... bizarre. They will happily cook me appropriate meals that they share themselves when I visit them (I live far away so don't have many chances to see them currently). Though they feel this insistent need/desire to constantly mock me about my diet. I don't ever mention it. For example, today is my birthday and I picked up some sausages etc to make a nice meal and they asked what I was cooking when I was on the phone with them. I said sausages blah blah blah and my step father was instantly like OH PORK ONES RIGHT!?! HA HA HA HA HA HA HA HA HA. I immediately said, "that isn't funny. you've been making these jokes for how many years now? Thought you would have gotten some more material by now..." They do it all the time, on the phone, in person.I'm all up for a joke but it's so often and overkill. I have stated clearly that it isn't funny and it's actually hurtful. It feels like they don't take me seriously and it makes me not want to speak to them. I even specifically try not to mention anything food related. They understand the reasons behind me eating this way and know I have been doing it for a long time.How is the best way to communicate with them that it's a) very hurtful and annoying b) makes me not want to speak to them. I have told them this but they don't care clearly as they keep saying them. Even my partner thinks it's out of line (he eats meat) and has told them several times to stfu and that it isn't funny. My mum tried to get the dog's pork ears one time to wave them in my face but luckily my partner shut that down quick.Any advice welcome, I'd love to keep speaking to my parents. Please don't make comments about it's my fault that it's my diet blah blah blah. Y'all can eat what you want, I'm happy to sit in the corner eating my plate of food (I don't like to share anyway...)TL;DR, Parents mock me about my diet to the point where I don't want to speak to them. How can I tell them to stop even when I've said it's hurtful etc and it clearly makes me uncomfortable. via /r/relationships https://ift.tt/2HBgSJu
