> a bourgeois-liberal perversion and appropriation of the energy of these movements

Sounds like a deflection, and inaccurate. The issues don't arise "outside" of the movement, they spring inevitably when there is enough traction and zeal because the mob doesn't understand nuance. Mobs are dogmatic and orthodox, and everything is a nail. The Fabians (a bougie socialist club intent on popularizing Socialism) had this fear about laymen should Socialism be in vogue, the Catholic Church about the Bible being interpreted by the public, etc. - they were all correct. Media of course is in it for the money, they just do what they've always done which is exploit salience.
