Yesterday two or three people remarked that I periodically ban people because they voice differing opinions. This spoke more to the posters’ shortcomings — a slight difficulty with accuracy and fairness in their writing — than to mine. I ban people who resort to personal slurs and a general tone of confrontational ugliness. I’ve said this until it’s coming out of my ears, but I’m using the same standard any person giving a party in his home would hold to. If a guest becomes coarse and abusive, he/she would be asked to leave. Is that really so hard to understand?
