"Let's say you disagree about some conspiracy theory but there is an author on Steem producing content supporting that theory."
I will downvote anything that is a lie like pizzagate. Or that goes against coventional scientific wisdom like Anti Vaccine posts. Its not about opinions or disagreement. This place is a cesspool of disinformation
Think it looks better from the positions of "orthodoxy" to actually articulate a counter argument demonstrating how it is disinformation.
It's easy to dismiss whole theories that are unpopular but takes a bit more effort to attack the underlying supports or things they use to try and substantiate said theory.
Also,I do believe it's healthy for scientific consensus to be challenged so the things we assume to be so can be re-examined. I mean people have believed some wonky shit take blood letting for instance.
