My interpretation of this silence is an evaluation of opportunity cost. I choose to be silent even though I might have something to say because I value the time saved avoiding a pissing match by forgoing any benefit of speaking my mind.
I might be totally missing the mark on her intended meaning. Regardless of my interpretation, it is pretty disheartening that advancements in various areas can be stalled due to people reacting (read wanting to be offended) rather than listening, processing and engaging.
It's not? Are you using some overly-strict definition of 'silenced' here?
I don't understand why you made that post after, in another thread, saying jmduke shouldn't have interpreted "silenced" that way.
Silence as a noun and silence as a verb are very different things. I'm sitting silent right now, but it's not because I've been bound and gagged.
I've seen this sentiment expressed often by prominent maintainers of open source projects, where they feel that their effort often leads to too much stress and negativity. Why bother with that, if you can just as well find a regular job that doesn't impact your personal life in a negative way? At some point, the passion of conviction gives way to the banality of everyday comfort.
It seems to me that the former is the less useful mode of analysis for long-term problem solving.
