"As a teacher, all of these are infallible as to Pope’s demand for absolute obedience of all catholics".  False.  Read up on papal infallibility, say with Wikipedia (not a catholic friendly source).  Also, maybe read up on the catholic magisterium, and learn the basics of the structure of catholic doctrine.  It might help with understanding the teachings you misrepresent, as well as how those teaching are structured and came about.  You don't have to agree with something to have knowledge about it.
