Yossi Sarids arguments against Gemara are not his original arguments. They can be found on many hate sites and at least one of the arguments used (the brachos) I believe can be traced back to martin luther (you can google these arguments and see where they take you). Recent events are not the source of the hatred in his article, but are likely the cause of him repeating them at this time.
Was Sarid ever exposed in a meaningful way to a yid or yiddishkeit that exemplified diracheha darchei noam?
