How will that initial scan take place? On your device, or sent to a server? Once you give the authorities that ability, will they stop at CSAM, or will they flag anti-israel content as well?

The government doesnt get to read every message I send and see if they deem it sendable or not. Thats the problem

If you think this would stop at CSAM then you're naive.

What if they decide tomorrow that critisising the government is unlawful? That you get arrested for being LGBTQ? Send "Free Palestine" at your friends and have cops at your door?

If they allow this scanning, they just need to edit a text file to immediately flag thousands for having certain beliefs.

Besides, the real criminals will just move encryption to a different level or find different ways to bypass this.

Ultimately, there's only one solution for governments. That is to ban all encryption. And hopefully that's something we never see happening.

These same people are at the same time taking away freedom of speech to support a genocide. How do I know they won't scan for pro Palestine content?

They scanned your message and found you were critical of Israel, a team has been sent to your location to resolve the issue.
