I wouldn't be so hard on this essay. It's a little scattered, but there's some gold in there. Writing a concise, powerful essay is really, really hard, which is one of the reasons that people who are really good at it become famous (Jonathan Swift, Christopher Hitchens, etc).
Thanks. Usually I have a 1-day/500-word minimum between initial writing of anything like this and posting it, because I don't want to embarrass myself with mediocre writing. I like to have days between drafts.
This time, I want a message to get out, and fast.
I might rewrite it in a week or so. Pretty much all of my 2000+ word blog posts deserve to be more than one post.
