In USA, why are Europeans and Middle Easterns grouped together, yet Asians, Pacific Islanders, and Native Americans are NOT grouped together?

Thats where they choose to live, no one is forced to be in these groups, they want to live among their own kind.

So that jews can be grouped with europeans.

You may be assuming that Europeans and Middle Eastern people are "grouped" 

together, but from the prospective of DNA,science,  Statistics and Census they are not.Asians, Pacific Islanders and Native Americans are separate groups because they have separate scientific classifications.Asians are all related to various Asian countries.  Pacific Islanders are people who have mixed ancestries that include Asian, European,  and Aftician,

To pretend that humans come in races

well demographicly they are grouped together but europians and middle eastern people are not seen as the same group of people

Middle easterners are racially white. 

Who in the US groups them with Europeans?

Middle easterners are Asians. All those people are culturally too different to group them together.

Nothing in your post made any sense whatsoever. 

Since the first clause of your ignorant rant is false, it follows that what results from it is also racist factless garbage.

middle easterners are not european, their asian. native americans are not asian because they are native to america so their american. pacific islanders are hawaiian.
