Nope.  Neither should they.  One can support a Pope as an improvement over previous popes without supporting church teachings that contradict Gospel commandments such as with the ordination of women.  It is always sin to hate and discriminate like with racism or sexism and the Church Magisterium can't make what Christ has declared sin a righteous form of behavior.  Most Papal Loyalist agree abortion is a sin & against church law but they don't see how church law & civil law need to be the same since they have different goals.  Our treatment of baptized Christian Church members who are homosexual has been repugnant - Do not condemn else you will be condemned is in the Gospels spoken by Christ.  Papal Infallibility is supposed to be utilized only when the pope is reciting scripture or a dogma, it does not specify anything a pope says is perfect or that popes can't sin which Pope Francis admitted to soon after election by identifying himself as a sinner.  Who claimed God can't judge us?
