The refugees leaving through Egypt don’t?

How could they? Reiterating my prior point:

They are killing them as fast as they think the international community will tolerate. They won't kill them fast enough to provoke any major entity into opposing them, they will just stay firmly in the "everyone will wag their fingers at us and argue about whether it's right" zone, which is where they sit currently.

So the fact that this leaves open the possibility that some people get to flee their homes in terror, knowing that their friends and loved ones who refuse to be chased out of their homes by Israel are likely to be killed by the IDF, is one of the things that you feel might convince me that Israel doesn't have genocidal intent?

And what will make you believe genocide isn’t the end goal?

Clearly nothing that you're going to accept.
