There are some long lists of false beliefs that programmers hold. isn't because programmers are especially likely to be more wrong than anyone else, it's just that programming offers a better opportunity than most people get to find out how incomplete their model of the world is.
I'm posting about this here, not just because this information has a decent chance of being both entertaining and useful, but because LWers try to figure things out from relatively simple principles-- who knows what simplifying assumptions might be tripping us up?
The classic (and I think the first) was about names. There have been a few more lists created since then.
Time. And time zones. Crowd-sourced time errors.
Addresses. Possibly more about addresses. I haven't compared the lists.
Gender. This is so short I assume it's seriously incomplete.
Networks. Weirdly, there is no list of falsehoods programmers believe about html (or at least a fast search didn't turn anything up). Don't trust the words in the url.
Distributed computing Build systems.
Poem about character conversion.
I got started on the subject because of this about testing your code, which was posted by Andrew Ducker.
Some Christians do. I know some [EDITED: previous word was "one" before; don't know why I did that] who don't. Anyway: yes, there are more and less aggressive ways for someone who believes that to say it. Of course however you say it it's a much much nastier thing than anything VoR has ever said about transgender people ("these guys are likely to suffer worse torture than a million Auschwitzes, and it will be exactly what they deserve"), and contrariwise in many cases the person saying it will only half-believe it and will be deliberately avoiding thinking about it too much. But yeah, there's a huge difference between "unfortunately temporal sin has eternal consequences, and the only way to escape eternal damnation is to put one's faith in Christ" and "those godless suckers are going to burn in hell, and I look forward to watching them do it", and again a large part of the difference is that the latter seems hostile and the former (if sincere) doesn't.
The two aren't quite equivalent (e.g., I think you can be hostile purely inwardly, whereas aggression is necessarily an outward action) but they're closely related.
It wouldn't be. If someone is acting oddly, then "Alice is suffering from depression" would be not at all aggressive and "Alice is fucking crazy" would be (if expected to reach Alice's ears) quite aggressive.
Should I have? Yes, in general intent matters; to take an extreme example, if I am a speaker of a foreign language and some perfectly innocuous sentence in that languge happens to sound exactly the same as "I'm going to kill Lumifer and eat his brains" then there's nothing aggressive about my saying that (unless e.g. I know full well how it sounds and say it with the intention that you should hear it and be intimidated, while preserving plausible deniability for me).
(Hostility implies intent, doesn't it? It's not as if nothing I have said so far addresses the question of whether intent is relevant.)
I'm pretty sure there are circumstances where it doesn't matter whether something was intended aggressively but only whether its effect is the same as if it had been. But for the purposes of determining, e.g., whether "the left is the aggressor" here on LW, the actual intent is more important. Of course the effect may be easier to determine than the intent.
I think you're probably right that neoreactionaries tend to be intelligent. I don't think Tumblr-SJWs are at all uniformly stupid, though (in fact my guess is that they're less stupid than the population average in terms of raw brainpower), and I know some people who are both very clever and quite Tumblr-SJW-y. I think LW would probably route them to the woodchipper almost as directly as it would the stupid ones.
And why do you think this would be the case? Purely because of the ideological bias?
I think one of the defining characteristics of Tumblr-SJW-y people is that they are highly aggressive, both by your and my definitions. I suspect that it is their intolerance which would make them not welcome here.
