Nobody ever proved that Jews killed the Duma baby. All evidence points to clan rivalry... and subsequent instances of this clan-related violence hasn't been reported by YNet because it doesn't conform with their assumptions and hopes that the general public is gullible and subject to manipulation.
The big problem here is that This is incitement and propaganda. Demonization no different than once found in the pages of German newspapers.
YNet and Shin Bet's troglodyte 'Jewish Section' are exaggerating, and in many cases setting up scenarios to 'prove' their conspiracy-theory claims. No balanced reporting here as there's rarely (never) any focus on the actions of Muslims in the region that occasionally cause Jews to respond (in the famous 'kick under the table' way).
We could easily live in genuine peace with our Arab (Muslim & Christian) neighbors were it not for the actions of YNet & Shin Bet. But, in Israel, defending those who work to destroy the Jewish State is allowed. This situation won't last... and it's more likely that the Left and its Shin Bet allies and provocateurs will get the worst end of the stick. Their arrogance prevents them from seeing that the majority here don't support their ideology.
