It wasn't deliberate. I wasn't grokking what you were saying. I was reading:

  Many people talk nice, but [niceties are] all bullshit.

Instead of:

  Many people talk nice, but [their talk is] all bullshit.

The ambiguity of that 'it' is really what this stemmed from.

So, basically you might be talking bullshit here. There is NO correlation between being a verbal assh*le and being efficient. People can 'deliver' without insulting others. Linus is a high headed rude man, and there's no need for that. You can be straightforward and succinct without being insulting.
