Can you tell me what the word "racist" means?
I can't give you necessary and sufficient conditions for someone to qualify as a racist, if that's what you're looking for. I can give you a general (although probably not exhaustive) sense of attitudes/beliefs that I would consider indicators of racism, and I can point at examples of people I consider racist. Given your subsequent request for a taboo on the word I'm not sure what purpose this would serve, but I'll do it if you'd like.
Can I in the future expect you to stick to the same usage?
If by this you mean something like "Can I expect you to set down a definition of racism and accept in the future that only people meeting that definition are racist?", then the answer is "no" unfortunately. Like I said, I don't think I can articulate a necessary and sufficient set of criteria for identifying racists. If you're asking if I can be expected not to be disingenuous and slippery in the future, then the answer is "yes", I think.
Can we continue this conversation while holding to a rationalist taboo on "racist"?
Sure. I'm not the one who introduced the word into the discussion. But I'm not sure what this conversation is about, exactly. Would you like me to tell you what I find objectionable about Derbyshire without saying "racist"?
ETA: I'm not sure how advisable it is to continue this conversation, actually. I don't think discussion of this specific point contributes much to the community, and it is the kind of political clutter that people have objected to in the past. The situation seems to be this: I find certain things Derbyshire says morally repugnant and indicative of a culpable prejudice against black people. You (I'm assuming, otherwise this is just a semantic debate about the word "racism") don't. I'm sure you've read the sorts of arguments I would make before and been unconvinced. I'm fairly sure I've read the sorts of argument you would make and been unconvinced. I doubt either of us is going to get anything substantive out of this discussion, and the mind-killing potential is huge. So let's drop it, yes?

Yes because I think the strong moral revulsion the average Western person has towards "racism" comes from ethics based on sacredness (I recommend your read Tinkerbell ethics series by Sister Y to see what I mean by sacred) and not due to consistent application of utilitarian ethics.
Not to say lots of "racism" might not reduce overall or average utility, but the same could be said of the targets of other emotionally charged arational revulsions. For...
Summary: Current social psychology research is probably on average compromised by political bias leftward. Conservative researchers are likely discriminated against in at least this field. More importantly papers and research that does not fit a liberal perspective faces greater barriers and burdens.
An article in the online publication inside higher ed on a survey on anti-conservative bias among social psychologists.
The link above is worth following. The problems that arise remind me of the situation with academic and our own ethics in light of this paper.
I can't help but think that self-assessments are probably too generous. For predictive power of how an individual behaves when the behaviour in question is undesirable, I'm more likely to take their estimate of how "colleagues" behave than their estimate of how they personally do.
This shouldn't be surprising to hear since to quote CharlieSheen: "we even have LW posters who have in academia personally experienced discrimination and harassment because of their right wing politics."
While I can see Lammers' point that this as disturbing from a fairness perspective to people grinding their way through academia and should serve as warning for right wing LessWrong readers working through the system, I find the issue of how this our heavy reliance on academia for our map of reality might lead to us inheriting such distortions of the map of reality much more concerning. Overall in light of this if a widely accepted conclusion from social psychology favours a "right wing" perspective it is more likely to be correct than if no such biases against such perspectives existed. Conclusions that favour "left wing" perspective are also somewhat less likely to be true than if no such biases existed. We should update accordingly.
I also think there are reasons to think we may have similar problems on this site.
