Your claim was about brainwashing, and I think, hate. There's no shortage of that in Israel, especially among right-wing/religious sectors, all the more so when referring to the illegal settlers in the West Bank.
This is not about justifying, accepting, or supporting Hamas - but it cannot be said that such elements do not exist in Israel - it's just that they are not as strong as Hamas, and despite expected objections from the usual suspects, in comparison they are under control. Obviously the main difference being one fully embraced and celebrated by Hamas, while Israeli governments (even right wing ones) aren't 'there'.
Here's a choice one (the 'Blood Wedding' too, if you care to look it up)
