That’s not true. Within a short time of forming, all the surrounding nations attacked Israel to ensure they wouldn’t exist there. Israel’s opponents regularly targeted civilians with indiscriminate bombings since that’s what their morals produce. They planned to keep doing that over time, too. Keep that in mind when interpreting everything else.
At times, Israel allowed for a two-state solution but Hamas wanted every Jew there dead or gone. They’d push them into the ocean itself if allowed. People called for Israel reducing their presence in Gaza for peace. Doing that led to more attacks instead of more peace.
Recently, Hamas killed and kidnapped civilians on purpose. Whereas, Israel warned people to leave before the invasion where they then focused on military targets. If people stayed and were connected to those, they’ll likely die during the invasion. The OP is about people who stayed that are mostly connected to militants. OP writer pities their families but not all the non-militant families Hamas killed.
While both sides are plenty guilty, one is actually aiming for peace, focusing on military targets, and reducing civilian casualties. The other broke peace, attacked civilians, and called for more genocide. The difference between these two strategies shows that anyone wanting long-term stability with less murder in the area should support Israel.
Also, Israel is allied more with us while their opponents keep funding terrorist groups, including our own enemies. They’re also strong, economic partners. Why on earth would we ditch our friends to back people who do little for us and support our enemies?
