The role of any socialist approaching modern culture is as a critic. There is no such thing as socialist culture and trying to create such a thing is at best misguided.
Just because something is said in the bourgeois press does not make it untrue let alone something that can simply be written off. Modern mainstream culture is bourgeois. The prevailing ideas in any epoch are the ideas of the ruling class; this includes ideas about law, justice and so on. Most people we want to reach are, to this extent, 'bourgeois'. If mainstream press attacks a part of the socialist you deal with it head on, you don’t dismiss the attack and you don’t hide, because you can’t.
