I've recently had a slew of comments from an anonymous poster. I've resorted to deleting these comments from my blog and changing my settings so that all comments must be approved by me before being posted. I hate to do this, but one person can ruin it for everyone.
I don't mind opposing views being posted on my blog, but when a person insults me, bullies me, and questions my faith, I draw the line in the sand. If you disagree with me and want to say so, by all means do, but do it in an intellectual, respectful, and charitable manner. If you are incapable of this, don't bother wasting your time or mine, for your comments will be deleted!
