With Koreans and Indians, I'm doubting gang initiation. As you've brought up, I'm wondering how many data points they're basing this warning on. As you said, some neighborhoods could be over represented with different ethnic populations. I live in one with lots of people with Chinese, Korean, Indian, etc backgrounds, in part because they're drawn to the local public schools.
I think you're right for the Indian community (and as you, I use this term generally, as an ethnic category, as I know a lot who prefer to simply be called Americans) ... but I know many of Korean backgrounds that are not gun averse. Most of those that grew up in South Korea, of the men, put in compulsory military time (something like 2-3 years). They might not have gun rights there, but many embrace these rights when moving here.
