From all I've seen, read and heard, the settlement in Hebron is the showcase for the worst that settlers can do. A tiny colony of Israelis is maintained within a Palestinian city. A full and detailed account of the situation is provided by the Israeli NGO, B'Tselem.
This video, not from B'Tselem, but episode 64 of the series Sleepless in Gaza and Jerusalem, provides an intimate view. Reporter Ashira Ramadan, accompanied by a Palestinian resident of Hebron, comes across settler children playing in the street. In response to her attempt to be friendly, these 5 somethings insult her and one even wields a stick. The final cry of one of the children is "get out, you dog". Go to 11:45 to see the interaction with the children.
You also should meet Alfred Ginsberg, a settler, apparently from Brooklyn, who denounces "Hussein Obama" as a racist among other insults he doesn't hesitate to voice. Go to 20:10 for Mr. Ginsberg.
The entire video is worth watching.
