I don't think anyone is telling you to radicalize random photography bloggers on Twitter. Like, whether you see radicalizing people as your personal responsibility is neither here nor there to me, but I'm pretty sure you're supposed to start with people you know and are already comfortable talking to. It should start with people you have or can develop a rapport with.

And even if you want to use online spaces for some kind of praxis, Twitter is the worst possible place imaginable for it. It's like going to a football game and hashing out politics with people sitting on the other side of the field.
