Except that this is not just weird and far-fetched. It is also very unusual for such diet-based discrimination to happen.
I am a vegetarian. All managers (with the exception of one) who hired me in the past 12 years (in India) were not vegetarians. Unlikely that they saw vegetarians discriminating, and did not practice a little reverse discrimination themselves.
The problem today in India is not that there is a caste competition between one caste and another, it is that the IT field is desperately in need of developers and testers. And, the employers are unable to pay the high salaries being demanded.
The instance being described is mainly in the US, where the talk described was given. I know that such discrimination is highly unlikely, especially in the Midwest where there aren't a ton of Indian employees to begin with, and probably even fewer Indian hiring managers.
However, I was merely stating it as an example of caste discrimination – which you seem to grasp readily, probably because you're Indian or work in India.
Explaining to an American person how diet-based discrimination can be an instance of caste discrimination is harder than you'd think. The OP is basically going "I saw an Indian person doing this bad thing, so it must be caste-based discrimination!", which I'm trying to correct by citing an example of (so to say) actual discrimination on the basis of caste.
