You're so full of it. The role of a FT is questionable and so is the qualification. Anyhow, you may keep at it here just like the folks in Falklands have it erected for their queen.

The nationality of a teacher should be important because only Native English Speakers should teach English(as an FT;) therefore, a Russian or German should be rejected in the same way as an African should be rejected. No special exceptions should be made because of the colour of your skin, black or white. Clearly they shouldn't have laughed at the hapless African before they rejected him. You say "The have been caught laughing at an African man" Who was it that caught them?? They should have politely told him that their policy was only to employ teachers from -Canada, UK, USA, Australia, New Zealand, Ireland, Falkland Islands, Jersey and maybe other British dependencies who only speak English.
