It's an entirely appropriate reply to your self-important sarcasm.
It totally demeans any posible legitimate argument you may have
Now that's plain stupid. I would think that your interest in the subject is serious and not dependent upon your opinion of me. Thus you would make your own judgement about the value of the works or Shusteff and Zhabotinsky.
Especially the latter given that
a) He was responsible for Jewish entry into WWI on the side of the British and thus largely responsible for the Balfour Declaration
b) He created the Israeli army
c) He predicted the Holocaust and was largely responsible for saving whatever part of East European Jewry that was saved
So now I'm stooopid.. and I have no opinion of you other than you seem unable to make a statement without some personal derogatory comment.
