Just Curious Count, What does it take for you to erase someone's comment on sight. Are you that insecure in your own stance that you are afraid to even allow someone with a different viewpoint to state it.
Hell, if I knew I was right about something, I'd welcome opposing opinions with open arms, just to give me an opportunity to prove how right I was.
Then again, if I knew my arguments were shaky, I guess I'd be afraid of having to publicly try to defend them too.
Of course you can look at Bob's blog and either he is erasing opposing view points or nobody is posting on his blog.
