Consider "In rural areas, which reflect the dominant lifestyle of human beings for 10,000 years, it was common to have many hours alone to think while performing labour. Hence it's obviously not a privileged mode of thought."
In other contexts I just want to fucking vent about some stupid shit that dumb people say. But I'd suggest this site isn't the best place for that, and I wouldn't expect such a tone to help people consider my point of view more carefully.
If you use expletives all the time, they lose their value, which is the ability to make a very strong point, such as expressing utter disgust.
Also, HN tries to be more than just your average internet message board, and making it just a little less informal may be what helps keep it a generally civil place. Our comments are going out to the whole world here, not just to a small group of our friends who have similar backgrounds and preferences.
It is difficult to replace such an intensifier as "fucking" without simply using a common replacement (bloody, for example). The most neutral I could come up with is something akin to "counfoudedly", and naturally one would do away with the word "very". Another simply worded option would be to repeat the word "very" once or twice more. I'm more likely to use the latter in some spheres online or with my mother or in an English speaking workplace, especially in the US. (Norwegians seem a bit freer with expletives, especially the English word "fuck").
