The speed with which ATEK went from being a blog issue to being reported in the Korea Times speaks to the insular nature of Korea's English-language press. It reminds me a bit of my university paper, which was written by the people who read it, and the only people who read it were the ones who wrote for it. Reactions to articles and debates on letter pages were severe, but they were limited to the group of, at most, 50 people, who were part of the cliquish group of campus journalists and those with agendas to push.
Much of what gets reported about foreign teachers or foreigners in general might be true, but the better question, as advocates of English teachers often point out, is why it's reported in the first place. It's not entirely the sensational, often false reports that manage to link, however tenuously, an English teacher with disease or sexual abuse that this argument refers to. It's also the surprisingly regular articles or pictures showing foreigners wearing a hanbok or making kim chi at a department store.
Similarly, the campaign ATEK has launched against the Anti-English Spectrum, which to my knowledge has not harmed or adversely affected an English teacher in Korea outside of the Internet, is a little over-the-top. If harsh words against every minority in the West by xenophobes and racists merited this sort of attention, the Urdu and Arabic-language newspapers here would be filled with reports about the European-based Anti-Islam Facebook group, which has almost 3,000 members, and the Korean-language press would have a field day with the racist remarks on the de facto online home of English teachers in Korae, Dave's ESL Cafe.
The point is that not every slight, insult or slur is something to worry about or deserves a response. Presumably, most foreign teachers are white and have never been a minority that was abused by some members of a majority group. Immigration regulations like criminal background checks, as well as drug and HIV tests, which have been legally challenged, are simple compared to the six-page medical check that Canada requires. Entry to America, until very recently, was not possible for tourists who were HIV positive.
On the other hand, it would be ludicrous for a minority group to let itself be walked over, presumably a group that is well-educated, relatively wealthy and relatively well-organized (there's a message board, if nothing else). But groups representing ethnic minorities in the West don't squander their time, energy and resources protesting malicious but otherwise harmless websites. The effort spent trying to clean up AES could have been spent on the sort of lobbying that might bring about improvements, however small, in the lives of foreigners. The current course of action seems to indicate that many English teachers have simply never been insulted.
