When it is demonstrated he is highly unorthodoxYou have demonstrated nothing of the kind. I'm sorry, but unorthodox means teaching heresy, nothing more, nothing less. The Pope has not done so. It is unjust and inaccurate to throw the word around like that without any substantiation.
Being heretical would involve a break with Catholic dogma whereas being unorthodox implies espousing doctrines which are unconventional and untraditional, but not necessarily heretical. Big difference.
