The bias works both ways. I work in a largely male, scientific environment like Mochajava described, and for me, it is paradise. I can be myself entirely -- no pretenses, no holding back. I can give everything I have and it is appreciated. Then I step outside, anywhere else really, and it is not good enough. I have to play the mind-games of wondering what people REALLY mean by what they say. I'm expected to emote when I have no wish to and nothing to express. I'm surrounded by a cacophany of other people's feelings that all seem like so many slippery eels. There is nothing I can grab onto. I'm expected to engage in social rituals beyond common courtesy, whose only purpose seems to be making others feel comfortable. I will do this for those close to me and whom I care about, but it gets draining quickly.
All of this is simply a criticism of the external environment, and not of the necessity of coming to terms with one's own internal emotion-scape. As Mondo mentioned, however, detachment from emotions is a legitimate technique for doing this, and in no way equates to denial. In fact, the ability to detach may reduce the negative physical manifestations of emotions. I have been pondering one concern, though. Are there cases where detached consideration is not effective or appropriate? Can one become overreliant on this method, and if so, what is the detriment? Are there better ways to deal with emotions, particularly negative ones?
I cannot say I have ever considered emotions inherently irrational or stupid, but I have lately been considering some of the same questions both Shmoooooo and Halla discussed in their posts. I would be interested in learning what I can about the importance of feeling from those more adept in this area.
