I have read some but not all of his other articles, and I thus far have found little support for the statement that he's specifically anti-Palestine. Maybe I missed something, but the main thesis seems to be that people claiming to be pro-Palestine are very often anti-Israel or pro-Hamas instead, based on mysteriously failing to take pro-Palestine positions that are also pro-Israel or anti-Hamas, and mysteriously taking anti-Israel and pro-Hamas positions that aren't pro-Palestine at all.
