That's implying a false equivalence. If I make a quotes page of a public person, a person with far-reaching goals, in order to highlight problematic beliefs this person holds, beliefs that would otherwise be lost in a vast amount of other statements, then this is not the same as making a "random stranger X sucks" page.
Then again, LW does not have a "Why Anything Sucks" page as far as I'm aware. There are plenty of people/organizations out there with whom LW/MIRI disagree, and who are more visible than you, but I don't think LW has ever gone out of its way to make posts on why those people/organizations are bad. The fact is that in order to promote good discussion, you just don't want to have a page saying that the members of website/organization with whom you're having the discussion suck. (And while you might call it "highlighting problematic beliefs", the simple fact is that much of what you've posted about LW/MIRI is mean-spirited and hurtful, both of which are qualities that I don't think most "highlighting problematic beliefs" pages have.)
To be clear: much of your criticism is constructive criticism, possibly valid. Another significant portion is neither constructive nor valid. But regardless of whether it's valid or not, you do not want to be rude or confrontational about it. If your intent is to improve LW/MIRI, then you want to phrase your criticisms in a way that makes them pleasant to engage with. From what I've been able to tell based on your posts and comments, both here and elsewhere, arguing with you is generally not a fun thing to do. Do you think people will be more receptive to stuff that's phrased aggressively, or less receptive? I have very little to say on the object level in response to your concerns. However, if your goal is to foster improvement, then it's probably a good idea to present the objections without the snideness. It makes it a lot more comfortable for both sides of the discussion if you do so.
You said that engaging in discussion with representatives of LW/MIRI is stressful for you. It doesn't have to be.
Then again, LW does not have a "Why Anything Sucks" page as far as I'm aware.
You may know me as the guy who posts a lot of controversial stuff about LW and MIRI. I don't enjoy doing this and do not want to continue with it. One reason being that the debate is turning into a flame war. Another reason is that I noticed that it does affect my health negatively (e.g. my high blood pressure (I actually had a single-sided hearing loss over this xkcd comic on Friday)).
This all started in 2010 when I encountered something I perceived to be wrong. But the specifics are irrelevant for this post. The problem is that ever since that time there have been various reasons that made me feel forced to continue the controversy. Sometimes it was the urge to clarify what I wrote, other times I thought it was necessary to respond to a reply I got. What matters is that I couldn't stop. But I believe that this is now possible, given my health concerns.
One problem is that I don't want to leave possible misrepresentations behind. And there very likely exist misrepresentations. There are many reasons for this, but I can assure you that I never deliberately lied and that I never deliberately tried to misrepresent anyone. The main reason might be that I feel very easily overwhelmed and never had the ability to force myself to invest the time that is necessary to do something correctly if I don't really enjoy doing it (for the same reason I probably failed school). Which means that most comments and posts are written in a tearing hurry, akin to a reflexive retraction from the painful stimulus.
<tldr>
I hate this fight and want to end it once and for all. I don't expect you to take my word for it. So instead, here is an offer:
I am willing to post counterstatements, endorsed by MIRI, of any length and content[1] at the top of any of my blog posts. You can either post them in the comments below or send me an email (da [at] kruel.co).
</tldr>
I have no idea if MIRI believes this to be worthwhile. But I couldn't think of a better way to solve this dilemma in a way that everyone can live with happily. But I am open to suggestions that don't stress me too much (also about how to prove that I am trying to be honest).
You obviously don't need to read all my posts. It can also be a general statement.
I am also aware that LW and MIRI are bothered by RationalWiki. As you can easily check from the fossil record, I have at points tried to correct specific problems. But, for the reasons given above, I have problems investing the time to go through every sentence to find possible errors and attempt to correct it in such a way that the edit is not reverted and that people who feel offended are satisfied.
