"Did Jon Stone write those excerpts cited?"
For a start, I saw no excerpts - only unsubstantiated one-line quotes, but let's look at a couple.

"Last year Richard Falk, United Nations special rapporteur on human rights in the Palestinian territories accused the Israeli government of "ethnic cleansing" by trying to replace Arab Palestinian populations in its territory with Jewish Israelis."
This is a long standing accusation coming from both outside and inside Israel – I believe it to be true, based on Israel's long-term behaviour towards the Arabs – I think you yourself have said on numerous occasions that the Arabs have no right to their homeland because they've only been there (for how long?)and should go and live among their own people.
What on earth is that if it isn't "ethnic cleansing"?

Israeli settlers have also been accused of violence against the existing inhabitants of the land they build on.
So.....?
Chemical sprays and high pressure hoses have been used with boring regularity to get farmers to leave their land – not just by the settlers, but by the army as well.
Some time ago I put up a film of an Arab family being manhandled out of their home because a bunch of settlers fancied it.
The British left to the sound of hand-grenades being tossed into occupied houses by Israeli "freedom fighters" – go read Benny Morris and Einstein's and the list of Jewish intellectuals' letter – a matter of history.
If it wasn't actual violence, it was threatened violence backed by the forces of Laura Norder.
