As a skeptic, I would agree that I would not claim to know so much. I have lots of hypotheses though.
And, as a skeptic, you might think that there would not be much to say... but then I find myself swimming, nay drowning, in a world of unfounded opinion and hearsay. So much baseless belief. I think I can see the contradictions and unfounded assumptions in whatever narrative is being presented. In good faith, I try to point out the errors as I see them, to the best of my ability. I think of this as a service - helping to discern belief from knowledge.
But evidently it is not appreciated. I am flagged, people think I am hateful (I don't believe I am). In all, people do not appreciate the genuinely skeptical position, even if they pay lip service to it. They prefer to go along to get along - to do whatever their unprincipled, lightly considered, free-style way - whatever is most expedient at the time.
PS: 'I am posting too fast' so I cannot submit this response. Its not that I don't want to continue the conversation, but HN puts a block on unpopular opinions such as mine. Skeptical voices cannot be heard! But I will try to submit this in a few hours (it was 3 yesterday), even if the conversation has moved on by then. :)
Does it amaze you that freedom of speech to have a different opinion to others, one that I think I can reason and evidence, should prove to be something that requires censure? I'm amazed. Did you think that HN was better than this? I did.
The thing about a position of extreme skepticism, such as you are expounding here, is that if you acted consistently with holding it, you would not have anything to say.
