Instead of getting angry you could research what that slogan means to different groups. For nearly every group that slogan currently means freedom for everyone from the river to the sea. Most accounts of early use meaning freedom for Palestine not just from Israel, but from Jordan and Egypt as well. The one group that used it in a mostly genocidal undertone was the PLO in the 1960’s who believed it meant returning the whole region to Palestinian rule, and ‘removing’ all people that immigrated in the last hundred years. As with most things it requires nuance. It can mean something bad, but these days most people use it to mean freedom. Intentionally taking it to mean something other than how people mean to use it seems disingenuous.
