Someone deleted a post they thought would be inflammatory. I didn't think it would be a problem, and took no action when I read it, but neither was it necessary to post telling people to ignore whatever the posters you were ignoring were posting. The 'flamers' in question have recently been making on-topic and reasonable posts, with no reason believe they would cause any problems.
FWIW I would have just locked the topic if it had started to become a problem, rather than delete the post.
