He said America is full of conceited fools (ok thats an OPINION) who only care for themselves (now that is an assumption)

He lives in canada and obviously doesnt care about any country except Canada most especially America, so by saying Country A doesnt care about Country C and living within Country C and 'attacking' Country A he has indeed contradicted himself. Now I cant help that your head is thicker than concrete bro, I wish I could but I cant

<you are correct, contradiction is an opposition of ideas or forces; Not a grammatical error>
