While I do encourage discussion, frankly, there’s a point where I don’t care. If you don’t add to the discussion, are pointedly being rude, misogynistic, pig-headed, and so forth, I always reserve the right to delete or revoke any commenting privileges. Spam by teenage boys is automatically deleted. Indeed, if you are a minor who is posting nonsense, I will delete your comment. And, yes, your comment must be approved before it appear. I will read whatever you write. Remember that. I may use what you’ve written in a future post.
