I feel there are enough debates with flat-earthers, climate change deniers, covid-deniers, anti-vaxers etc. and it leads to nowhere. (at least in .cz) The same applies to other topics, for example some time ago there was Internet censorship in .cz widely discussed (a topic where I can be, given my education and job, absolutely sure what things are nonsense from the technical point of view), and I think the problem is arguments from the "objectively correct" side are indistinguishable to a layperson from the "crafted nonsense". For a layperson to make sense of such arguments, at least a several hours long lecture explaining the concepts would be needed (in case of vaccines: DNA replication, proteosynthesis, folding, antigens and immune reactions…; in the case of internet censorship: routing, DNS, HTTPS, SNI…), which is impossible to do in a "debate", we have "lectures" for this. Otherwise, they simply cannot get the arguments and why the other side is wrong, by other means than faith. And yes, of course there are many websites, free online textbooks and recorded lectures explaining such concepts available to anyone willing to spend some time on it. Even in Czech, so no language barrier.
