Some Jews who keep kosher do the same thing. We assume that meat at a restaurant will not be kosher unless it’s a kosher restaurant. I would assume that the same would hold for meat being halal. I’ll eat fish in restaurants if I know it’s a kosher species of fish- kosher species of fish don’t have to be treated in any specific way to be kosher. That’s not the case for kosher species of birds or mammals, though. AIUI, halal animals (mammals, at least- don’t know about birds) also have to be slaughtered and the meat treated in a certain way for it to be halal.
And then there’s the fact that, in most cases, it’s much simpler to say “I’m vegetarian” rather than to list the things you can and can’t eat, especially if you’re not a native speaker of the local language. Saying you’re vegetarian might also make it more likely that your dish won’t contain meat stock or be cooked with animal fat.
Same thing with kashrut- you can’t make a dish kosher by picking off the bacon or whatever. And, of course, a restaurant or cook that makes a dish with beef would have no reason not to use beef stock in it, which you can’t pick out.
Would they eat lamb as well, or is that just something that Indian restaurants in the US serve because goat meat doesn’t appeal to most Americans? (I’d try it if I could find kosher goat meat, but that’s very unlikely)
Does that mean they have no religious restrictions on what they can eat (as it would if you said someone was omnivorous in the US), or just that they eat some kinds of meat?
I read somewhere that, within an ethnic group, dietary rules tend to be more restrictive for higher-caste people. Is that generally true?
I have read that alcohol is forbidden in Hinduism. Do most Hindus in India follow that rule? What about Hindus in the US?
AIUI, that’s not the same thing as the Christian concept of eternal damnation for suicides. From what I’ve read and heard, the vast majority of Hindus don’t believe in eternal damnation. If you don’t go to moksha, you reincarnate.
Do most Hindus hope or expect to go to moksha after their current lifetime, or do they expect to reincarnate a few more times?
Non-Hindus in the US aren’t necessarily that far from that situation, either. There has been a stigma surrounding mental illness and suicide until very recently- still is, in a lot of ways.
I’ve heard (from Slashdot, so I don’t know how reliable this is) that some Indian cultures put a very high value on education and getting a degree. Someone in the US might think of a person who dropped out of college to found their own company as a success, but people in those Indian cultures would not think of them as as much of a success, because they dropped out and didn’t get a degree. So there really aren’t as many alternative paths to success if you can’t hack it in a degree program.
