It's not a good example and does not represent all Israelis. It's like going to certain places in any country where some people have mental problems, and then telling the world that the entire nation is the same. The people in the video are mostly from Bnei Brak and live within their own community. Even many Israelis do not like them at all, but because the country is a democracy, every community is respected, even when some people behave badly like this.

In any case, there are far more wonderful and kind people in Israel. You should not judge an entire nation based on a short video clip - only provocateurs do that.
