Korea is w/o a doubt the most RACIST Country in the world I've ever had the displeasure of living in! I wish teachers would get a clue and avoid Korea. At least, until they start playing nicey nicey.

Seoul may be becoming more dangerous for Americans:
An email recently sent out by the American Embassy about danger in Seoul:

Subject: Potential Threat to US Citizens in University Areas

The U.S. Embassy is transmitting the following information through the
Embassy's warden system as a public service to all U.S. citizens in the
Republic of Korea. Please disseminate this message to U.S. citizens in
your organizations.

Recently, inflammatory sexual content was posted to a website for
English language teachers in Korea. That posting together with subsequent
postings were taken by some to demean Korean women. We have noted
recently, strong reaction in the form of web postings threatening attacks in
the vicinity of Hongik University and the Sinchon area against
Americans and other foreigners who speak English. All Americans and their
families (especially young adults) are encouraged to exercise prudence and
caution when visiting these neighborhoods. The Embassy advises that
inappropriate social behavior in public may be seen as provocative by
Korean nationals.

The U.S. Embassy in Seoul will continue to keep the U.S. community
informed of any changes in the overall security situation. The Embassy
encourages all U.S. citizens to register their presence in Korea with the
American Citizens Services (ACS) office at the U.S. Embassy or via the
Internet at http://travel.state.gov/travel/abroad_registration.html or
