I think more so in the Hmong Community. I don't see it in American society really.
For example, have you ever seen a white Christian person refuse to attend a party thrown by their relatives who are of a different religion? No, but I see it in the Hmong community all the time.
Have you ever seen a white person get so butt-hurt over someone observing their religious practices? No.
This country was built on the people's right to exercise religious (or no religious) freedom. If Shaman-practicing Hmong are deeply insulted then they divide themselves and NOT because Hmong Christians want to observe their religious beliefs.
Frankly, I'm pretty tired of all these unfounded accusations that the Hmong people are not united when that couldn't be farther from the truth. It's not because of religion or even our clan system. It's because some business owners and Hmong organizations aren't seeing the kind of profits/growth they expected. THESE ARE THE PEOPLE who complain about this the most. The complainers are sadly mistaken. They've somehow confused the fact that since the Hmong communities haven't been forking over money or participation into their businesses and organizations (resulting in slow growth for THEM), then it's because the Hmong aren't UNITED enough.
Here's something to think about (for profit and non-profit): Your service sucks, your product stinks, your business is poorly organized, and it's very transparent that you are completely self-serving. We're the customer and if you aren't giving us what we want/need then you can forget about getting our money or participation. Simple as that. When we hand you customer feedback you: cop an attitude, make excuses, or quit altogether.
Successful Hmong businesses don't complain about Hmong UNITY. In fact, the Hmong population isn't their only target audience. They know how to practice good business so it's unlikely to see them make a career change from being a Hmong grocer to selling life insurance to being a realtor to operating a translation service all in one year.
