Do you believe your opinions are more creditable than others?

To whom?

Be careful not to confuse credible with creditable. That which is credible is
worthy of belief or agreement. That which is creditable is worthy of applause.

For example: You state "Gould is the most
bigoted, closed-minded person I ever met",
(or attempted to state same), and whether or not anyone found your sentiment
credible, one of the usual high-fivers found it creditable.

I believe that insults and/or opinions conveyed by clumsy or careless language
are more than usually revealing. Insults always indicate more about the
insulter than his or her subject, but nothing beats a classic like, "I think
their is plenty of evidence that you is stupid."

My advice to you, or to anyone else who cares to express opinions about other
individuals, would be to frame those observations in complete sentences with
some attention to grammar and syntax.

It is so easy to sound juvenile when making negative personal comments. It
becomes more important to avoid a sloppy, careless, use of the language
that reinforces an impression that you'll have to get off line when Dad gets
home and catches you playing with his computer.
