This thread is the most disappointing thing I have ever read on this site, and that is saying a lot. Do you guys think you are funny for making fun of a Vegan and posting images that would obviously be upsetting to that person? You're acting like inconsiderate jerks (putting it nicely). 
I do, and you should too. Vitamin B12 deficiency is not just a vegan health issue, it can affect anyone.
So very true. I consume meat, yet I still have B12 deficiency. In my case, I cannot extract the vitamin from food properly.
I have to get a B12 shot every few months. It can definitely affect anyone.

It can be VERY disturbing for some viewers, so I will put it inside a Spoiler tag.
Is that real? Because I seriously just cried my eyes out after seeing that.

I think I just became a vegetarian.
