Troy,
The problem is that there are some boards where deletions are a nigh daily occurrence and are sometimes based (arbitrarily in my view) on who made the post or the content of the views. If a poster expresses a political view different from one of the moderators or one that the moderators find offensive, the post gets deleted.
You don't have access to the deleted posts and cannot possibly know what content they had, so how can you make that statement?
Personally, I have only ever deleted one post and it was one containing what I thought to a totally unacceptable phrase: "raghead, sand n**ger" was the exact phrase used. In fact, it was used by one of the folks who wants to give moderators unbridled control over off-topic boards and is a moderator on more than one of the threads where there are current problems. That ought to speak volumes.
Guilty as charged. Your deletion of the post was still censorship.
Have fun,
Phil
