This is a personal blog. As such, free speech is a privilege, not a right. It is a privilege I can take away from any one at any time if the need arises. To facilitate this, I screen all comments. This allows me to protect my identity better and allows me to prevent the posting of harmful, hateful, or otherwise nasty remarks.
Just because you disagree with me, or something someone else may have said in a comment here, doesn't mean you get to be invalidating or disrespectful. You are not entitled to a warning for bad behavior, although I may choose to give one.
If your comment doesn't not appear, it either did not submit correctly, or was rejected. If you feel there was a submission error, you are welcome to resubmit.
