Stereotyping Latinos for Latinos

One interesting episode of Latinos 101 involved the stereotypes within Latino culture of other Latinos.  While many may argue that these need to be let go to create one ethnic unity to strengthen the Latino identity for the greater good of Latinos, I felt that having this episode in the second season provided a greater level of authenticity in regards to Latino representation. 
Is this inter-Latino stereotyping offensive?  It could be.  However, it's something done in the United States as well!  I personally moved a lot growing up, so I heard and noticed all kinds of stereotyping of Americans by Americans.  Let's cover some of those that I've heard in my lifetime.

• In the South, people refer to Northerners as "Yankees" or "Yanks".  
• In the North, there are the opposing stereotypes of southerners as either very proper Southern belles or backwards rednecks.
• Texans are all cowboys.
• Texans say everything outside of Texas is a different country.
• Californians live on beaches and wear bikinis and shorts all the time.
• People say New Yorkers are rude.
• New Yorkers say people from New Jersey are wannabe New Yorkers.
• Pennsylvanians are all Amish.
• Midwesterners are all Puritan. 
• In Nevada, everyone lives in casinos and children don't exist (funny, since I grew up in Las Vegas and did NOT live in a casino)
• In Las Vegas, everyone grows up to be strippers or blackjack dealers (true in some cases)

How many times do we hear stereotypes within cities themselves?  Thinking of just high school or college rivalries, how many stereotypes exist there?

At what point does perpetuating these stereotypes about members in another group reinforce them?  Or could it be that they are taking ownership of their stereotypes and therefore ownership of their identities?

At the very least, while it brings up many of these discussions, this episode of Latino 101 (Culture Clashin') was humorous, but everyone was covered.
