Criticism of the state is fine. But the article is from a pro-Hamas site and has no credibility.
Not all criticism of the state is equal. When the Left criticizes the state, it is wise to view it with suspicion. There is plenty if criticism of the state from the Left (e.g., on NPR), and it is kooky.
When the Left criticizes Israel, it is motivated by a hatred against Israel and against God.
“Come and See” is not the pro-Hamas site that you claim. Nor is it even Leftist site. It is simply a Christian website in the Holy Land. It is a voice for a beleaguered minority. I would advise you not to demonize all criticism against the actions of Israel as being motivated by hate.
