In short
I got a reply from a prolific anti-vegan troll and referred them back to an earlier conversation we had. Got banned for "harassment" and "following someone around" when in fact they replied to me and keep following vegans around when they post against anti-vegan propaganda.

And the posts in question:
The comments when I posted them rendered as
Oh hey its you
The link is to a discussion which expanded is this here (The link goes to the comment with the highlighted star):

With background
The person in question is a very dedicated anti-vegan troll who is known to make non-sequitur claims as replies to vegans, in the hopes of roping then into a defensive position under the guise of "debate".
To exemplify this I engaged with them a couple months ago and got a perfect showcase of their behaviour. I had never used this and have never replied to them since then (at least I don't remember that I have and searching didn't turn anything up). But then when they replied to me yesterday I did. And got promptly banned for "harassment" and "following someone around". I messaged the mod who banned me to no reply.
Their behaviour is being enabled by lemmy.world mods like @aeronmelon@lemmy.world who will readily delete comments made by vegans should they dare step a foot outside of the norms of "civilized debate", like e.g. in the same thread (1) and (2). The petulant and incessant trolling by them is of course never subject to such moderation actions.
To any vegan comrades, do not engage this troll, you risk getting banned and your comments deleted.
Apparently I used wrong account to post this. Will have to switch accounts to my blahaj account on occasion to reply to comments, apologies.
If I were searching for people to agree with me I would post this to a vegan community. I'm looking to defend myself against the accusation of "following someone around" and "harassing" them.
As an aside I have heard the dietary reason a couple times now but never anything concretely about it and I'd like to learn more about it. Please don't see this as a reason to defend your right to live or feel pressured into replying in any way, I do want to learn more about this but you obviously are under no obligation to talk about your health on the internet to a stranger on the internet.
Also veganism is about minimizing harm, if you need animal protein to live then I'd consider that non-minimizable. I for instance require adhd medicine to function but unfortunately all the derivatives come with gelatin for the delaying effect necessary for it to correctly function. I consider this non-minimizable as well, since this is a choice forced upon me by society. There might be plant-based alternatives possible but they are not getting produced and I do not posses the means (or legal basis) to produce it myself.
Posting the whole argument doesn't support your statement about not stalking and harassing, is what I'm saying. I still don't agree with the mod action.
I added that for context, to be aware of when making disparaging statements about eating meat.
I don't understand the biological reasons myself. I know I feel like shit (sluggish, sick, can't sleep) when I go more than a week without about 6-10oz of meat-based protein, which aligns with what the nutritionist told me. She said people like me need 1-2 chicken breasts a week to stay healthy.
I stick to low-impact meat products, rely on a couple hunter pals, and only buy what I can eat. I still eat a lot of fully vegan meals, vegan sausages, tempeh, and mix in a lot of vegetable protein to "beef up" traditionally meaty recipes. Avocados and beans and all that. I always have eggs for a quick "pick me up," but they aren't enough to fill the meat gap.
Cooking skills helps. I probably wouldn't have tried a vegan diet if not for that job, and probably wouldn't have put as much work into figuring out my needs if I didn't have some very cool, conscientious, knowledgable people around me, like that nutritionist. Not everyone knows why they feel/need the things they do. Like you, most of us are just trying our best.
