The equal rights were 1947 borders set by the UN, which Arab nations rejected and started a war which they lost.
If you look at the map, “from the river to the sea” clearly means the whole area.
The original slogan also was “from the river to the sea Palestine is Islamic/Arab”, but that would be far less catchy in the West.
As for equal rights in democratic state, that has to be a joke. Just look at population of Israel where almost 25% is Arabic and compare it to Palestine which is very homogenous.
Nethanyahu is a MF, far right politician that should spend the rest of his life in jail, but let’s not pretend the other side are saints. They would would do exactly same (maybe even worse) if they had the means.
There are no good guys on either side of that conflict, just innocent people caught in the middle.
