The limit on comments is 3000 characters; after that it cuts off the rest of your comment. By clicking "preview comment" before publishing, you can avoid having your message truncated.
A few suggestions: Try limiting your comments to the topics presented in the post, although I realize this may be difficult as they have wide implications. Avoid ad hominem attacks and focus on the arguments at hand as much as possible. Finally, proofread your comment before you click "publish" - poor grammar and spelling only hinder the communication of your ideas.
On that note, thank you all for the comments and contributions. Keep up the great discussions!
