You can see him interviewed here on France24 where he claims to support peace, and also that he cannot return to "Palestine" because Israel would arrest him because of his support of Palestinian rights. When pressed about whether he attempted to return home, he said that he had been detained for hours at the airport but he never says that he was not allowed back.
Even so, he has supposedly applied for asylum in France because of his oppression. He does have residence there but as far as I can tell he never received asylum.
He told the Jerusalem Post in 2014 "“I have many Israeli friends from my work as a peace activist. ... I believe in peace and support peace, because violence begets violence.”
This post has been taken down, apparently. But he has also compared Israel to Nazis more than once, which is pure antisemitism:
He also calls for Israel's destruction:
When he claims to be a peaceful man who is oppressed by Israel, he is not telling the truth.
