These protest have been going on for years.
The idea that Israelis generally support him is part of his media narrative, not reality.
The fact that the protests were getting bigger and louder before 7.10 is another reason war was allowed to happen (it keeps people distracted and united against an enemy that isn't him, and the results are instant - many already saying to wait with holding him accountable until "after the war" as if he wouldn't start another or make this one last until he made sure he couldn't be removed).
When he went to visit the front lines, he didn't only refuse to meat, but expelled reservists who were called in to duty who were known to be at protests or signed letters against him.
They have now also made it legal to shoot protestors with live ammo and arrest anyone suspected of "interfering with military operation" (this is mostly to target Palestinians and Arab-Israelis, but also Jewish protestors)
The Israeli government doesn't represent the Israeli people.
