The leaders of religious communities AFAIK are elected by a small group of politicians. Politicians and rabbis are fallible like anyone else. What he said pertaining to non-Jews isn't a part of normative Jewish belief, practice, or law anyways. Just like how Wahabbi clerics calling non-Muslims apes and pigs has little to do with what Islam teaches I imagine.
1- It's just Hatefull speech , inspite that there a verse of Quran talk about the punishement of group sinners of Jews by God ,God transformed them to apes
so some extrem muslims used it to general , that's.
Prophet Muhammad (pbuh) : asked to don't calling Jews "apes" .
this may help (in arabic ) you can translate it to English

2-if I am correct even the Bible called a group of Jews , "serpent" ?
3 it's not Talmud verse said (as meaning): "Jew are Adam and , non-Jew is non-Adam" ?
Judaism DIR doesn't prevent you from asking questions about Judaism or it's practices. If you want to pretend to be an authority on Judaism however, you can do that in the debate section.
I posted couple threads in Judaism DIR ,everytime i discuss , they ask me "to stop discuss , because it's break the DIR rules" , so i decide to not post thread in Judiasm DIR since i feel that i want to discuss .
