As I've occasionally mentioned in posts before, comments to the Saga are screened before they are published. Yes, I reserve the right to decide what appears on my blog.
I seldom refuse to publish a comment. If someone disagrees with me, I usually want their comments to be seen. Either they made a good point that I should address, or they helped me make mine through their absurdity. Most of the comments that I've refused to publish have just been spam.
But let's make no mistake: if I don't publish your comment, I'm not infringing on your freedom of speech. Respecting your freedom of speech does not require me to let you stand on my soap box. You can start your own no-cost blog just as easily as I did. That's why I have multiple blog articles that respond to Allecto: I understand that she blocks critical comments and that she has every right to do so. I can be critical of her on my own blog.
This is not a response to any complaints about my actions: it's a general broadcast. I've seen people complain that so-and-so screens comments on their blog or doesn't allow comments on their YouTube videos or "unfriends" people on Facebook. So what? It's their blog, their channel, their Facebook account! They have no obligation to publish anyone else's opinion. If you want to say something, you can start your own blog or channel. Your freedom of expression is not infringed just because someone else doesn't give you free access to their media channel.
End of rant.
