You start with general rant about intelligent people being sometimes wrong. Yes, we know it. It's one of the reasons we call this website "Less Wrong" instead of "Always Right".

Then you give examples of wrong moral reasoning and their refutations. However you write it in a way that would make an uninformed reader think that those errors are typical LW errors, because you attribute them to LW people, but fail to mention that they are used on LW as examples of wrong reasoning. So an uninformed people would probably think "really, those LW people are insane, if they don't see such an obvious error". But we do. You just avoid mentioning that.

And then you continue with political mindkilling. You seem to have a talent for this.

May I suggest reading some relevant Sequences?
