I suppose it depends on who the podcast is for: if it’s to dispel western capitalist propaganda about socialist countries, (i.e, @millennialchaos’ Radio Free America; which dispels propaganda against People’s Korea) who’s target audience are liberals in the Imperial Core; repetition of certain points is helpful to bring a point across to as many people as possible. When it comes to ML podcasters, the more people influenced by them, the better.
In short; you, as an ML; probably aren’t the target audience for the podcasts you are referring to.
Fair enough. Still, it couldn’t hurt to have more of them; or the existing ones gaining more popularity; in my opinion. There are pros and cons to any format of agitation; podcasters and influencers are 1) more modern, and 2) More effective when it comes to radicalising the younger generation, in particular. They just aren’t for everyone, and that’s okay.
