Most of the observant Hindus I’ve met do not eat beef because cows are sacred to them, or so they have told me. They do eat other forms of red meat in my experience, unless they chose to be vegetarian. If I haven’t grasped all the nuances involved well, I’m not a Hindu myself and I can’t be expert on everything.
The fact I am not an expert on everything is, to my mind, a very good reason to not confront people in public about stuff, especially personal stuff like gender identity, who they do or do not have sex with, dietary preferences, their religious views or lack thereof, and so on and so forth.
…because it’s generally considered rude to start an argument in public with a stranger?
There are a lot of instances I don’t agree with what someone says they are and how they act, but I don’t say anything to the contrary because I don’t want to expend my energy on arguments about things that are, by and large, none of my business.
I’ve met a deluded victim of J4J’s once. Every other one has turned out be a predator. I generally start off with 'You are of course aware that Jews For Jesus was in fact founded by a Christian who changed his name to Moishe?" and similar questions. In the (It hasn’t happened yet) event they were genuinely unaware, I will politely fight their ignorance.
I wish folks who expend this much thought about edge cases for trans people and outward expressions of gender identity and could instead spend more time thinking about why society has inculcated such strict social binaries on them and what’s so important about continuing to cling to them.
In India (which of course is not the sole arbiter of validity when it comes to Hindu identity, but in practical terms is pretty determinative), somewhere between 1% and 2% of Hindus eat beef, while 44% of Hindus identify as vegetarian.
So yeah, beef-eating Hindus are a very small minority among Hindus, but there are still over 8 million of them in absolute numbers.
