If you look back into the thread, it wasn't me that put the screenshots up, it was someone else, which is why I challenged it.
However if you are in any doubt, there are plenty of verified tweets, videos, statements and more that Israeli officials have said, on TV, on Twitter and on official channels, whereby they are expressing genocidal intent.
It's not hard to find verified sources for these things. Such as this newspaper article outlining many of the statements made.

“We are fighting human animals, and we are acting accordingly,” Israel’s Defence Minister, Yoav Gallant, said, describing the Israeli military’s response just days after Hamas’ attack. “We will eliminate everything - they will regret it,” Gallant added.
"There will be no electricity and no water (in Gaza), there will only be destruction. You wanted hell, you will get hell," Maj. Gen. Ghassan Alian, who heads the Israeli army’s Coordination of Government Activities in the Palestinian Territories (COGAT), declared.
“There is one and only (one) solution, which is to completely destroy Gaza before invading it. I mean destruction like what happened in Dresden and Hiroshima, without nuclear weapons,” he said.
In another statement, Feiglin said Israel’s end goal should not be to eliminate Hamas, but rather, “Gaza should be razed and Israel’s rule should be restored to the place. This is our country".
