If "from the river to the sea" implies a mostly contiguous 2-state solution, it's not offensive.
It usually implies the end of Israel in a recognizable form.
A two state solution or a one state solution both would result in the end of Israel in its currently recognized form so that's not saying much. Basically you end the apartheid and suddenly Israel is unrecognizable because it has to change in fundamental ways.
