If you meet a conservative, you’ll probably only know he’s conservative from long term observation. There are, obviously, some loud exceptions. But if you meet a vegan, you’ll likely know he’s a vegan with just five minutes exposure. Being vegan is an essential part of their identity. But it’s not an obvious part, like a beard or breasts, so they have to tell you, lest you should “identify” them as just some ordinary person. They’re special and they want you to know about it. Kind of like the early adopters of the electric car. THEY were saving the planet.

Vegans border on being a religious cult.

Sound like a description of a bicycle zealot, too.

Yup—there is nothing more irritating than homo sapiens who insist on proclaiming their virtue.

They are dangerous to children and other living things.

There’s a ‘joke’ that goes something like:

How do you know if the person you just met at the bar is a vegan? ANSWER: He’ll tell you within 5 minutes.

Sometimes it's just a FYI in case you two become friends and go out to eat somewhere. My ex is one of them. He's a gun-owning truck-driving Trump supporter but he wants some tasty vegan options when going out to eat. Sometimes it's simply that.

I just tell them that they are what they eat, a vegetable.

I have found that Vegans mirror gays in this. Always feel the need to tell people that their proclivities define them. False pride or secret desire for acceptance? I suppose it doesn’t really matter, it’s just annoying, to me.

Or a Linux user.

A few years ago, there was a Russel Crowe movie called “Land of Bad”.
I thought one of the best jokes from the movie was:

Q: How do you know someone is vegan?
A: They’ll tell you.

For them it’s not food it’s a cause. It doesn’t just fill the stomach, it’s an emotional catharsis - defines whether they’re a good or bad person.

You mean as somebody NORMAL?
