I don't think the poster is being too hyperbolic. A very large share of the most vocal on both sides of the political aisle prioritize narrative over truth. Literal truth is less important to these people than something that is maybe not 100% true but captures 100% of what they feel. Tools can help these stories spread less wide but they will not be able to prevent the most ardent from continuing to use these stories as cornerstones of their beliefs. This is probably a small fraction of the country overall but a large share of the active on political X/Twitter.
