I don’t speak American

Can someone translate

This man said that his severe lack of

• education
• basic decency did not allow him to
• speak any other language than the one he was born with
• know that this language is called “English”, and an “American” language does not exist
• realise this was a flaw rather than a badge of honour proudly to be worn in a diplomatic context.
