I don't think you can generate antisemitism if it isn't already there, and the marches aren't necessarily doing that.
However, the marches are provocative and the behaviour often morphs into antisemitism, like their abusive chants. Earlier I mentioned that more of these marches will only incite more public disorder, and several posters agreed by requoting me. Allira is right that they whip up emotions, even if they are peaceful.
I did find it strange growstuff /sunami that you immediately jumped in asking me for links regarding incitement to murder, when that wasn't mentioned at all.
