Other forums do not suffer from this particular political lean. Reddit mods in particular are known for authoritarian ban hammering because its the only way to quiet ideas that go against their worldview, and they often approach it as a holy war that they should control the information that is visible to the public eye so they can protect the public for them, and that the public themselves are unable to decide what is right or wrong by themselves. Political discussion is often so skewed on reddit the term hive mind is not only a term used to describe the website userbase, but also observable in real time.
Hacker news doesn't suffer from this, thankfully, the moderators do not think its appropriate to manipulate or outright silence any viewpoints dangerous to the reputation of their ideologies. Which is why we're allowed to have these types of discussions here in the first place. On reddit, however, I have written statements that have been moderated away I presume "for the safety of the public" as if the public could not decide on its own. Don't assume that everybody on the planet agrees with that kind of sentiment. Go out there and talk to your right wing nutjob friends. They have differing opinions. Just because you don't see them on reddit doesn't mean they don't exist, nor that they are not normal people with normal opinions either.
You can label it a conspiracy theory if you want. But that doesn't eliminate the presence of the facts from which the conspiracy theories have arisen, nor does it eliminate the the presence of covered up removal of those facts for the sake of engineering truth.
You are just unaware of the world beyond the veil of your lived experiences. But it doesn't help that your emotions are so tied to your defense of your ego.
