The Cardinal knows this. Pope Benedict taught in his letter to the Bishops, accompanying the motu proprio Summorom Pontificum, that the SSPX is within the Church, that it is not a schism. Burke dissents on this formal teaching of the Supreme Pontiff ironically taking the unorthodox position opposed to the Pope, claiming recently to another internet Professional Catholic that the Society is schismatic.
Folks, the Society is not schismatic. It is one of the best examples of maintaining the Catholic Faith during this Crisis. To speak or act as if the opposite is the case is disingenuous. Cardinal Burke needs to re-read what Pope Benedict said and issue an apology to undo the damage he has caused toward the Society in this and past interviews, if he is an honest man.
