Give me a break! There is only one "other religion" which objects to this, and that is Islam, which has been proven to have attached no great significance to the Temple Mount until very recently. Christians recognize that the Passover is a foreshadowing of the sacrifice of our Lord, which occurred during the Passover.
Normative Judaism no longer practices animal sacrifice. No Jews in Israel-- secular, Orthodox or Haredi (ultra-Orthodox)-- want to sacrifice a paschal lamb on the Temple Mount. The people asking to do this are a tiny, tiny fringe group.
