Orange Curtain
The Orange Curtain is a local term for the border between Orange County and Los Angeles County in the U.S. state of California. It is a sometimes derogatory, sometimes lighthearted term that is used to describe Orange County's more conservative and suburban population as compared to the more liberal and urban population of Los Angeles.
The phrase is a wordplay on the so-called Iron Curtain which separated communist and capitalist Europe.
According to Colleen Cotter, "Because has a reputation for political conservatism, people from Northern California especially worry about what happens 'Behind the Orange Curtain'."
The Orange Curtain began from the fact that between 1890 and 1950, Orange County was wholly white and "the region's predominately Irish settling also embraced an ideology of small government.
