Conservatives speak up all the time on HN, and weirdly enough they sound exactly like you do, down to the inability to refer to the left without a pejorative.
That's actually the label the left has taken on themselves, blaming conservatives for it is really weird. Yes, the behavior of the modern left has little to do with the classical liberalism, but it's not the conservatives' fault that the left took on themselves this mantle and then failed to live up to it.
