I think that the OSS community (and IT community in a broader sense) has this idea that "they're just words," and so therefore, they should just be able to say what they want without consequence. But, words matter. A whole lot. Empires are built upon words. People rally around words. Words convey ideas, thoughts, feelings, and everything that goes with them. Why is rampant bullying accepted in this culture? Why is it the norm?
I'm not saying that things have to be all sunshine and rainbows. Yeah, sure, it's stupid to read a byte at a time, but you don't have to be an asshole about it. You can say, "Hey, that won't work," and be done with it. People should be treated with a modicum of decency. Remember the human, and all of that.
