Maybe it would help if you read the conversation again. I'll paste here for convenience:
>>>>>> Linus just being Linus (paraphrased).
>>>>> That may be so but I'm pretty sure that pretty much every study that's been done on this says insulting people is demotivating and generally destructive behaviour.
>>>> He has not insulted any people though. He has said bad things about the piece of software called gcc-4.9.0, but he has not once in that email adressed a person in a negative way.
>>> Uh, do you think GCC just spontaneously sprung forth into being? No, it was created by people, and Linus is indirectly insulting them.
>> As a number of people have already commented, when Linus posted the bug report to the GCC project, he was careful not to insult them.
> Do you think those people exist in some sort of vacuum where they don't have access to (or will become aware of) the kernel mailing list thread?
Did you really intend to say that a person can only be insulted if they are insulted in every place a particular issue is discussed? Or are you saying that if a person is treated kindly in at least one avenue, then it doesn't matter how many others they may be insulted in (i.e., the one kind treatment negates all the other offenses)?
