I think the Southport africans were right in that Israel has committed genocide and war crimes. They are on a par with Russia in Ukraine.
Israel was attacked but it should not have wiped out pretty much a whole country.
What were they supposed to do though?
Keep in mind that Israel was not just attacked on October 7th, they've been under almost constant rocket bombardment over the years and have been talked out of retaliation by allies including the US who helped them devise the world's most sophisticated air defence system, which constantly shoots those rockets down.
The Hamas attack demonstrate the extent to which Hamas had upgraded their capabilities and it became a threat that could no longer be ignored.
The only way of dealing with it was attacking it in a military operation.
Now Hamas are not a conventional military force, and in pretty much all ways are drawn from, interlinked with and indistinguishable from the civilian population in Gaza. This was illustrated when many of the crimes committed on Israeli soil were not committed by Hamas, but by civilians that poured into the breath created by Hamas. Hamas themselves admit this, saying that they don't hold all the hostages and do not know where they are being held in Gaza. Basically, Iran and Hamas lost control of the situation and ended up creating a situation they never intended to create.
There are no military targets in Gaza, Hamas fighters live with their families in civilian buildings. Civilians that are not part of Hamas but yet are still armed have likely taken shots at Israeli troops.
Military doctrine is that if an advancing military column comes under fire you call in airstrikes or artillery to take out the building the fire is coming from. There's videos of US and British troops doing this in Iraq and Afghanistan all over YouTube.
Everyone claimed Israel had a right to defend itself and that destroying Hamas was a legitimate aim. If you accept that you also have to accept its going to be a blood bath where the normal rules of engagement and international law do not apply.
