Debby,

rabbi Faur is a member of Conservatism and is not fit to speak on Judaism.

As Arakim said, in the time of King Saul, G-d sent Samuel the prophet to commanded Saul to wipe out the entirety of the nation of Amaleik!
Saul failed to do so.
Saul kept their king alive for one night and in that one night he raped a woman which kept the seed of Amaliek alive.
Haman was a direct descendant of that union.

"On this Purim day..." it is most fitting to attach one's self to the Judaism's chain of tradition which was accepted lovingly and whole-heartedly by world Jewry in the days of Esther.

The Torah calls Yishmael 'pereh adam.' Not a man who appears wild but wild who appears a man.
