And they used terrorism all the time. We remember them as this great non-violent social movement because it's convenient to, but they killed loads of people, including a bunch of Africans.
Difference is, they didn't deliberately target civilians, nor did they gloat over their deaths.
No, just no. The ANC primarily targeted civilians. Bombing shopping malls and such like they did, is pretty much guaranteed to only harm civilians. I would say they didn't care who they killed so long as they were white, but that's not entirely accurate because they killed even more black people than whites. Furthermore, while not having access to tanks and such (which would have been entirely useless in the civil war.) the ANC was quite well armed by their friendly ties with most old soviet block and communist nations.
The Palestinians cannot avoid civilians. hell, they can barely even harm Israeli civilians as it is. The people doing the settlements are not the Israeli military but building contractors and police, all of whom are civilians essentially. Last I checked even, those bottle rockets which are pretty much all the Palestinians have available to them, have such a short range they cannot even reach the original 1948 borders of Israel from the current Palestinian lands.
Hell, think about what caused this recent slaughter. 3 Jewish kids were abducted and killed. In any other country, this would be seen as the work of a serial killer or at worst an isolated incident of hate crime. Given the victims were all children, serial killer is more likely. However, the Israeli governments response to discovering the bodies is to proclaim "Hamas is responsible and Hamas will pay" without any evidence whatsoever. Of course with such a proclamation and essentially support from the government, is it obvious that a group of Israelis will then go and execute a random Palestinian child in a revenge attack. After which everything spiraled out of control into the usual and current Israeli slaughter and bombing of Palestinian territories.
Lastly, air strikes, Israels current favorite method of slaughter, by their very nature are indiscriminate. Bombs dropped by aircraft are useless at fighting terrorists, but they work wonders at beating an uppity ghetto back into submission for the next wave of expansion.
