1. "Pope Francis is not a gentleman and has many times made pejorative comments about those he considers traditionalists."
Deeeuuuh. Pointing out the flaws in a blind traditionalist attitude is not un-gentlemanly (what a quaint phrase) is not pejorative, it is part of his pastoral duties.

 2." If you really believe that 'the vast majority of Catholics in the pews' love Pope Francis, why are you so angst over Fr Weinandy's letter?"
Because one reactionary is a reactionary too many, especially because he can play on his former position to reinforce his opinion.

3. "If his letter is so obviously absurd, why does Mgsr. Strynkowski bother with a rebuttal in a Jesuit publication?'
It is called courtesy, because the author of the letter as a former-employee reflects on the USCCB.
