I moderate all comments. Spam is not allowed because it is annoying and, frankly, this is my blog not your billboard. On-topic comments critical of my posts are encouraged. We all grow through a healthy and respectful discussion. Hatefulness or name-calling whether directed at me or others, are not tolerated. Oh, I don't mind an occasional supportive comment either. We all need that sometimes.
If you believe I have not been true to this policy, please let me know. Perhaps, the policy is not clear or maybe I made a mistake. I am a fallible, imperfect human being with my own blinders.
