At this point laws like those in Germany only make the far-right's persecution narrative believable and give them more of an audience than they'd have otherwise, which the bourgeoisie don't really mind because the fascists always end up being the people they pay off to put down any challenges to the system if worse comes to worse for them. (see, Germany 1933-45, Italy 1921-43, etc)
I would more buy that, if anti-semitism was the major cause of the German extreme right. If we look at the violence commited by the German extreme right, the victim has rarely been Jewish, in fact if we look at violence against Jews in these countries, it's rarely the extreme right which are behind it. So I doubt they really care much about the whole ban against Holocaust Denial.
