No I do not think Mr. Cheetah should remove the comments he made. The apology he made should be enough and maybe an edit to that post for clarification.
People who remove things after they have posted them tend to look like children in grade school getting a "do over" to make everything look right.
All of us (most anyway) are both professional pilot's and adults and therefore we must take responsibility for what we say and do - even in this forum.
Just like the media we should be held to some measure of accountability - if at very least by ourselves as people and realizing that one unfortunate day "it could" be us on the spot. Either trying to defend ourselves after an accident or having our family read and listen to people comment on our alleged actions.
In short let us stick to research to support facts. If you are going to comment do the research and present the facts!
Therefore removing a post only serves to limit the damage to the person posting it. Take the hit and think twice next time.
