If not the Green Line, then what line should be the Israel-Palestine border?

It is not a fair summary: it’s intended to aggravate people who don’t agree with you. You can argue Israel isn’t being held to the same standard as other countries, but you can’t do so by comparing Israelis to animals - nor can you get away with it by saying it is the implication of someone else’s argument rather than your own opinion. I wouldn’t tolerate this kind of statement about other nationalities or groups, and I’m not making an exception for Israel. Don’t do it again.
