OrangeMarlin wrote "deprecated", not "derogatory". "Deprecated" means "not recommended to use". And both of you user funnier English than mine. (Like, OPrangeMarlin wrote "no scientific consensus doesn't change suddenly", so his sentence is quite flexible both ways. :-)

Thanks Max - I stand corrected on the mistake of Deprecated vs. derogatory.

I'm not sure how certain words are determined to be deprecated. Can you tell me?

As far as how fast scientific consensus changes, it is a small matter to me.

Thanks.

BTW, after reading OrengeM mans talk page I consider him a disgrace to Wikipedia. I support a permanent ban on him.
