There are many ways to describe most anything, and HOW they are described influences perception. You are certainly smart enough to understand that and know that the nuance of word usage affects the way people view the event. Journalistic integrity (of which there is precious little these days) requires the use of the least loaded and most accurate terms, and not the ones that a semanticist might argue are accurate enough on a technicality, but which give an entirely different impression. The term "sterilize" IMPLIES a much greater degree of permanence than does "contraception" as you well know.
This case is problematic enough without inflating it through the careful selection of terms calculated to magnify the significance of what has occurred.
Israel has many, many problems and one of these problems is the way their reaction to the persecution they face has resulted in a siege mentality that rises in militancy among a portion of their population that mirrors that which they face. The hard right in Israel IS a problem especially in terms of the intolerance they show towards that which is not Jewish enough from their perspective, but in order to understand the problem, people should understand the whole problem, which precious few do, especially those who only indulge in condemnation and demonization.
