Israeli here.

There is enough bad blood between us and the Palestinians for many people to approve the rape, and after 7.10 they feel confident enough to vocally support it. At least - the mob on the street and in social media. The more subtle right-wingers (as you may have guessed - this became a partisan thing) don't condone the rape itself - but they have a few "but"s:

• They say that the soldiers are heroes that operate in harsh conditions, and we should be more forgiving toward such "venting".
• They say that we should be more skeptic toward the testimonies of the released Palestinians prisoners, and should not start investigations based on their complains.
• They say that the arrest of the soldiers could have been done in a more peaceful and gentle way. (personal opinion - this argument is the only one that has some merit to it. Doesn't justify the rampage though)
• The rampage against the arrest is a legitimate democratic protest, and the establishment is only handling it with extreme prejudice because it's a right-wing thing.
