I think we tend to assume we're among friends (people who know what we know and have it in common with us) more than is actually the case, here.
There should be more discussions of breaking things down to first principles.
Things that are axiomatic.
What do we know to be true?
So many threads in which we fling shit instead of trying to reach a true consensus.
It's a double edged sword that everyone's anonymous. Communities like reddit with usernames / upboats become too agreeable, which is detrimental to truth.
The anonymity of this site makes it subject to things like slide threads from interest groups.
But it's more likely just retards being dismissed as trolls instead of people putting forth the effort to explain things.
