The settlers been at this for a long, long time. It was hard for me to understand their perspective as well, because surely they most be seeing what they do as something good, like everyone else. There is a BBC documentary that goes into more depth, but a short snippet of the documentary can be found here:

As far as I can tell, from talking with Israelis both living in Israel and outside, there really isn't one majority thinking a certain way, it seems to me that there is an equal amount of people cheering the settlers as there are people against what they're doing.
