I might point out that the job of the President (and all others in a political position) may be challenging.
Biden is a Catholic and has beliefs about what is right and wrong that derives from that.
Biden is also a patriotic American.
As a senator (and anyone as president) has sworn to uphold the constitution.
To impose his personal religious beliefs on others would violate the constitution. This is what makes the job challenging for him. If you expect him to ignore the constitution or you won't vote for him then you are utterly unamerican.
Trump reading from a prepared script looks a fool. In any debate he will splutter and waffle and lose track of himself before finishing a sentence (if he ever manages to finish a whole sentence).
Have you ever actually listened to the man? Ever?
