People on security forums have a natural tendency to maximize security and mountain climbers like high mountains very much. Although they are not typical in their interests, they are also typical, because most people have some special interests.
We should not criticize someone who chose very strong & layered security if this does not kill the computer and the layers are sensible. It would be like criticizing a good alpinist. Of course, the alpinist does not have to climb mountains, except that he/she likes it.
They are not guided by reason. They are guided by unfounded fear. That is a completely legitimate criticism. And not only that, it is how they allow an entire software industry to prey upon them, by targeting their fears.
In the face of uncertainty, one does not build a fort. That is a waste. Not only that, it does not solve the problem that they expect it. All it does is assuage irrational emotions. I mean, if people are here for emotional comfort, well you know what, that is probably why most people are here but they just don't know it.
As for the hobbyist nature of these sites, that is not real security. It is about playing with software and fanboyism. No different than gaming sites. Most of these forums have the same inherent problems as gaming sites - notably people not in control of their emotions.
There is no room for emotions in security. In fact, building security upon emotions is not real security at all. What it does foster is disproportionate security that is way out of line with reality.
I'm sorry but being paranoid is a bad thing. Everybody knows that. Yet I find it curious that people get all bent out of shape when you call them out on their paranoia and bad emotion-based behaviors. Reacting by emotion is definitely not OK. The mental health professionals say so.
