I don't think the problem is HN's collective view on taxes per se. It's the general black and white nature that refuses to see reality in shades of grey, which in turn causes that. For a community that so frequently pats itself on the back for being intelligent, you rarely see a nuanced discussion of anything. Taxes aren't all good, so therefore they must be all bad. Ditto intellectual property, Microsoft, etc.
I wish there was a month here where everyone had to argue the opposite point. It'd at least be a blast.
