Yes, there are fences and civilians in both pictures. The bottom picture is probably a border crossing. Israelis have been understandably paranoid about that border crossing since 2004.
Border crossings for pedestrians typically have fences (see the picture below, at a border crossing between the US and Mexico).
The difference is that Jews were put in Auschwitz to kill them.
I cannot prove that Israel is not trying to kill the Arabs in Gaza. However, I can offer a number of argument as to why, if Israel is committing genocide, it is doing an incredibly bad job of it.
- The population of Gaza is increasing. The graph ends in 2006, when the population was about 1.4 millions. However, the current estimate is about 1.8.
- Genocide usually does not include medical treatment, other than experimentation.
- Even Arab sources concur that Israel provides Gaza with electricity and water. It is to avoid a humanitarian crisis, but when you commit genocide you don’t worry about such niceties.
Proper disclosure: I lived in Israel until I left at the age of 24. I may be biased, but the facts I cite are still facts.
