The communist-led alliance has 6 seats in the Knesset. Their leader, Ofer Cassif, was banned from parliament for 45 days for saying that the current Israeli governement wants a 'final solution' for Palestinians. He joined the South-African case against Israel in the ICJ, for which zionist parties are trying to kick him out of parliament permanently. Members of their party are being arrested for their role in trying to organise protests for the rights of Palestinians and the police threatens everybody who's even vaguely associated with them. They support the right of return for every Palestinian (and their descendants) who fled since the creation of Israel.

So I wouldn't call them the 'moderate wing of fascism'. They have done a lot more than most and have done it in circumstances which are a lot tougher then many of us could handle.
