Uh, religion doesn't destroy anyone's culture. According to the American Constitution, religion has been separated from government and state laws. Therefore, I don't mind about having more than one religion. It's not the religion; it's what other cultures that practice without religion are attacking us. Culture vs. Religion is far different. Culture, I will say, "Yes, we should put some boundary on our people." As for religion, why against that?
I am a Christian; however, that doesn't mean I will automatically lose my identity. I don't want to lose my ID, nor losing my history and heritage. It's fine about the religion since as a Hmong person, I don't want to look like a anti-religious bigot. It's best for religion to be separated on its own.
You have LOST your Hmong cultural identity. Maybe not all, but most.
Of course religion is and part of culture. I will give you an analogy. Culture is like the body (entire body, from head to toe), while religion is a subset or part of it, such as the head, or torso, but it still belongs to the overall body. This should be obvious.
Hmong do not have a country, unlike Americans, so you can't entirely compare what we classify as a Hmong to that of an American. The difference here is that America has a defined territorial border, and governing it is a constitution. Anyone living within this border, whether white, black, yellow, etc, taking up whatever religion, is considered an American, as long as they meet the legal requirements of the land. It's a simple and clear cut definition.
To define Hmong is a bit more narrow or loose, depending on your view. We have no state. No place where someone can point his/her finger to and say ah-ha there's Hmongland, and anyone from there is a Hmong. Thus all we can do, and what we have been doing, is use culture (language, traditions, religion/supernatural beliefs, arts, etc) to define us and separate us from others. Think about it. These are what keep us together as a nation (nation is a group of ppl affiliated together, and don't confuse this with state, which is a defined territory which belongs to the said ppl). All throughout history we had/have similar "religious beliefs", that is until the 19th century when the white christians came and divided the ppl into two groups, of which the converters began self-hating... So when you turn into a christian you have SUBTRACTED and ERASED so many Hmong cultural practices (mostly having to do with the supernaturals) and replaced them with a foreign one. Do you or your parent have the xwmkab in the house? How about noj pebcaug for your place? Call spirits back for yourself or your kids and family members? I gave you those examples already in many of my posts in the religion section. If you don't even practice these traditions anymore then are you even really Hmong, as you don't even fit into the definition anymore. Worst, you turn around and ridicule these Hmongess (for lack of better word)... So how can you be Hmong still when you intentionally rip these features out of your identity?... This is akin to someone revoking their American citizenship (not exactly, but similar) and still calling himself an American afterwards... You haven't done enough thinking about this. When you do you will see what I'm saying.
And you can't even really use genetics or "ntshav Hmoob" (which I know you think is the umbrella covering us all together) because so many of us have other dna components from Chinese, Viets, Lao, and even other non-Asians (from intermarriages/breeding). So "blood wise" we have differing degrees of genes. Even some Lao or Khmu over time have culturally transformed into Hmong (like they were adopted, or one of the parent is a Hmong). It's a hodgepodge with no real consistency.
