By "the “conspiracy theorists” keep turning out to be right" do you mean like how Trump won the election in 2020, Biden is an actor, Obama has been hung for treason, people around the globe are dropping dead from the vaccine, etc.? These are the people I'm talking about when I speak about conspiracy theorists, people reasonably sitting on the fence when there is conflicting information are not. You speak in absolutes about how _everybody_ who presented the possibility of a lab leak was banned and labeled a xenophobe, and while I cannot speak onto your anecdotal experiences, I never saw this in any platform I participated on at the time, in fact (as I shared in another comment on this thread), I leaned towards the likelihood of a lab leak after getting recommended a very popular youtube video on the topic from a very popular channel. As far as I know, that video is still available, although it has obviously been a long time since I last watched it.
Part of how cults are started is creation of a us versus them mentality, often where it doesn't exist. I believe this is why so many conspiracy theorists with more extreme beliefs might misconstrue their experiences in discussion around the topic, when in reality those discussing the very legitimate possibility of a lab leak never got much flak (anecdotally, as I said).
