That is because there is no other copy of Linus. There's plenty of other lesser software developers who can't do a tenth of what Linus did in his life.
I'd argue that in fact, there is circumstantial evidence that brilliant computer programmers can get work done without occasionally making those they interact with miserable: that evidence is the fact that most brilliant computer programmers get work done without occasionally making those they interact with miserable. There is nothing that requires Linus to make strong points by jumping and down and screaming. That's an affection he deliberately chooses.
There's a strong notion through this whole comment thread of "if he didn't do that, nobody would listen to him," which is absolute nonsense. People don't listen to him because of these kinds of outbursts, they listen to him because he's Linus Torvalds. They listen to him in spite of these kinds of outbursts.
Check the title of the thread you're in, and how many comments it has. People absolutely listen to him when he has these outbursts. It's usually a solid indicator there's something worth getting outraged about.
I am guessing you don't read the Linux mailing list if you think Linus goes off like this regularly. Maybe you're confusing it with the OpenBSD list and Theo.
Linus' comments like this make the news because of the content. If he did this all the time - frequently, as you posit - it wouldn't make the news all that often, as it would be normal. Linus isn't a guy who flies off the handle with regularity.
As sundvor already pointed out, Linus's cursing works. He uses it for emphasis, to bring attention to bear where it's needed. Being polite would likely be less effective.

So shouldn't you be OK with Linus cursing?
I disagree here too, though. Cursing is a choice, not a disability.
If, say, a firm fires someone for failing to maintain a civil tongue, I'd hardly call that a diversity problem. It could be quite reasonable, depending on the firm.
> I'm arguing against that the notion that this approach is necessary, not that it shouldn't be accommodated
Define 'necessary'. Would the kernel implode if Linus were more polite? Of course not, but I still agree with sundvor that Linus uses it as an effective tool. He's not just an angry child with poor impulse control.
