Hi Daniel, Stefan, Paul,
If somebody cleaned their home every day to the same standard as a hospital, most people would consider it extreme. But in the context of the hospital it would be desirable behavior.
On the other hand if you cleaned your home in the way a hospital is cleaned are you not at increased risk of infection, as you're not exposed to dirt, bacteria which is essential for your body to build up natural defenses.
I think any analogy will be flawed in some way :-) I also believe the perception of what is extreme depends on ones own position along the continuum which I believe we can agree exists. It's not a matter of black or white but many shades in between.
We can see the same in other debates: we tend to argue from positions we interpret as being black or white, where in reality we're talking about nuances. At the same time, it's somewhere along these continuums the fault lines of the free softare community exist and it is what sometimes causes fractures and splits in our community.
The debates we have, including this, are not meant to widen the fault lines, but to build bridges: to help understand the positions people in our community have. I do wish we would do more of it!
