Yes the Trotskyist were right about spreading their perspective. The problem with trot papers is not fact that it is a paper, the problem is what is written on that paper: boring Trotskyist rants that nobody wants to read.

A big part of news media, as Chomsky and Parenti and others like Neil Postman have written, is that the most successful news sources are focused on making things exciting and entertaining. If you fill your alternative news source with extremely dry socialist theory then very few people will pay attention. But if you make a silly comedy podcast from a leftist perspective then you can become so popular that you top the charts on Patreon and have a popular Reddit that is (initially) about your podcast, but then it gets banned but the fans liked the community so much that they created a new web forum that has however many thousands of members it is on here now.
