In the words of Linus, that's bullshit, and you're stupid for even suggesting it. If hating a subset of something is bad, then how is hating the whole better? Because it's more "fair"? It's also a lot more destructive, and misanthropy could be argued to include all -isms you could name, and then some.
Here's a thought, misanthropy is always projected self-hate, delusions of grandeur are just inferiority complexes, and Linus could use a shrink. Who doesn't, right? So I'm not judging. But if you're for calling a spade a spade, let's call a spade a spade.
