There is a [slight] difference between people pushing propaganda and those taken by it. Their actions are similar, but if the latter can be convinced to actually do their own research instead of being handfed someone else’s “research” there is hope of reaching some of them.
The real trick is ensuring they aren’t being assisted by a right wing truth bot, which the enemies of truth are doubtless working tirelessly on.
It may be pessimistic, but I don’t think we’re going to get very far in trying to convince people who don’t believe in fact checking to do their own actual research.
