Since they also call Sharon a Nazi, I guess that answers the question about Le Pen.
The liberals don't seem to know how to respond to Le Pen ---since they're against Jews themselves and have become pro-Palestinian, they compare him to Sharon but they know if they emphasize his anti-Muslim immigrant stance, they'll help him get votes so then they drag out the anti-Jew propaganda on him.
The liberals are against French and Israeli nationalism but they are in full support of the Palestinian nationalism. It's going to be interesting to watch this election because the liberals will be shown for what they are.
