"The Electronic Intifada" doesn't sound like a very balanced and unbiased source.
The “biased” video I posted is simply a recording of an interview of a survivor of the kibbutz on an Israeli talk show. Do you have any substantive critique of the video, besides just lazily dismissing it as biased?
If you watch footage from Nova you'll see large patches of obvious damage from Hellfire missiles, and footage from kibbutzes commonly show damage way beyond what you'd expect from handgrenades or RPG:s.
