I look up the first of those “human rights groups” and see that it’s explicitly a Palestine advocacy group with 38 employees. How’s this anywhere near objective?
There's nearly 200 citations in their report, citing a wide variety of Israeli and international media, medical journals, statements by the IDF, etc.

I assume the person you're responding to is not Israeli and has not been following this conflict very closely if they've never heard of B'Tselem.
