So if I understand correctly, you're saying that

1. you're more likely to be exposed to lies on a right wing forum compared to left wing forums
2. the types of lies you're exposed to are more dangerous in a right wing community compared to the left.

So first of all, how do you determine that #1 is true? I've seen my fair share of misinformation on Lemmy and the left-leaning parts of Reddit getting highly upvoted and vice versa. But I'm basing this on what I personally know (and who knows if I'm right?) and in general, there isn't much objective info going around. It's mostly people sharing their sentiments on a topic with little to no factual information (e.g. "fuck [entity X]").

#2 also assumes that you're right to begin with and that sharing these false statistics would lead to a better world. Take false statistics on police racism for example. This can be a problem in many ways. Let's say hypothetically that there is no police racism, but we say there is and we convince everyone that we need to fix it. This can divert resources away from other problems (e.g. working on reducing spousal abuse), and thus making problems worse elsewhere. Moreso if the police force is tasked with handling spousal violence and they're now tied up in internal investigations, maybe losing funding, and thus reducing their capabilities. It'll also be fuelling an unnecessary conflict (possibly violent) between people who should otherwise be allies in the struggle that is life. More people get hurt, more people can die. That's a pretty dangerous outcome.
