Not necessarily. You can be a vegetarian by choice (because you think it's healthier and/ or less cruel).
But the moment you add the word "pure" to define your brand of vegetarianism, you are passing judgement on others, and in India, that's often casteist.

Onion and garlic are both vegetables. If the word "pure" implies "no onion and no garlic", it's certainly casteist in origin, not rational.

Someone defined "pure vegetarian" as not eating onion/ garlic, someone else as not eating eggs. Since there is no standard definition, if the objective is to communicate dietary preferences, why not just describe.

Sadly, a lot of things that are considered a part of "tradition" have casteist roots. We can and must do better than celebrate them.
Do what you want, but don't boast about it.

When did I deny my privilege? Yes, I have privilege and with the privilege comes the responsibilty to attempt to put things right.

Semantics, Mr. Sahoo.
I didn't call anyone casteist. I pointed out that proudly proclaiming that you are "pure veg" is taking pride in something casteist.
After being told that, if you still insist on using the word "pure" I'll then call you casteist.

Choosing to eat vegetarian food doesn't make you casteist. But using the word "pure" implies casteist bias.
Regarding halal and kosher, they don't signal that your ancestors have systematically oppressed millions, do they? Caste system has.

Caste system has oppressed millions for generations. If you choose not to recognise that, you are certainly casteist.

After it is pointed out that the term has casteist undertones, if a person continues to use the word, they are certainly casteist.

Maybe Mr. Chesterton needs to consult the dictionary. By his definition, 'pure' vegetarians shouldn't consume dairy products either. They aren't of plant origin.

Our current vocabulary was largely determined by upper caste people who imposed their value judgement on certain words.
Which is why even non upper caste people also end up reinforcing the implicit judgment.

Bad example. Because if what Jains call "pure" is the standard definition, then most people will fail. Even carrots are not permitted for them.

Shifting goalposts.
Restaurants give people what they want to eat. And if people don't want fries fried in the same oil as chicken, it's their choice.
It's when people think they are superior because of those choices that it becomes a problem.

Yet another definition of "pure"!!!
With so many definitions, it's better if people be more specific, instead of using misleading words.

Halal and kosher both describe EXACTLY what's permitted and what's not.
I've found half a dozen different definitions of "pure vegetarian". Can't compare the two
