In defence of the moderators (and I've never knowingly met one) I think that their policy is to delete the offending part of the post and if necessary add a warning to the poster that if such comments continue they will be banned or similar.
This seems to be an old topic on which I can recall a few firmly held opinions before.
It is more likely I suspect that aisleman deleted his own posts, which is quite easy to do.
