Hamas members chanting "from the river to the sea" most certainly have genocidal intent, yes. Saying "from the river to the sea" alone - as the Likud document pretty clearly shows - doesn't make you a Hamas member nor a terrorist. There are a lot of attempts to conflate "Palestinian === Hamas", but that's sleight of hand.
I'm all for wiping out Hamas. I'm quite dubious about the possibility of doing so via armed conflict.
> A political party that calls for "Israeli sovereignty between the Sea and the Jordan" it is clearly a rejection of the "2 state solution" but that is not a call for the removal of an ethnic population from the region.
Maybe, but it's certainly a call for an un-free Palestine.
(Palestinians are rightly a bit leery of removal here; recent events have seen proposals to relocate them to the Sinai (https://www.haaretz.com/israel-news/2023-10-30/ty-article/.p... / https://www.nytimes.com/2023/11/05/world/middleeast/israel-e...) and a government minister suggesting nuking Gaza (https://www.reuters.com/world/middle-east/netanyahu-discipli...).)
"Free Palestine",as with other short slogans (see: BLM, Defund), encompasses a range of opinions. Both genocide and the two-state solution fall squarely within it.
