Regarding your initial set of links, I think it’s clear that I don’t consider these particularly credible. With that said, the accusation obviously has some degree of surface-level plausibility. But there’s more to genocide than “people are being killed”.

What about the Israeli government themselves claiming a (very dubious) 50/50 civilian-militant casualty ratio?

I don’t have any issues with that. I know, that sounds callous but considering that urban warfare and sieges always have exceptionally horrific civilian death tolls even without one side (Hamas) very deliberately placing as many civilians between them and the enemy as they can, I’d argue that those numbers are actually exceptionally good.

We’ve flattened cities in WW2 with better casualty ratios than that.

Not for lack of trying. Civilian casualties were basically a non-concern for the Americans (this is also true of Israel), and the Brits very deliberately sought out attacked purely civilian targets in a terror bombing campaign (this is not). Me saying Israels conduct reminds me of the Allies in WW2 was not a commendation of either. I consider both to be necessary evils to eliminate the Nazis and Hamas respectively.

What about prominent members of the Israeli government openly saying the intention is to commit genocide?

Ben-Gvir and his party certainly would like to turn it into a genocide, but coalition governments don’t work that way. A public statement from one minor coalition member doesn’t make something government policy. Otzma Yehudit has two ministers and six seats in the Knesset, they’re very much not able to dictate government policy. The fact that they haven’t been kicked out of the coalition over their remarks is concerning, but so far that’s all it is.
