Phyclaordgenspeciesusersslum is a word that I think should be used by creationists. It has a single synonym, which is "kind".
However phyclaordgenspeciesusersslum is far more honest.
With "kind" you can never tell exactly what the creationist is talking about. You can't see the movable goalposts with "kind" and you invariably end up asking for a definition that you end up wasting time trying to get them to pin down.
Phyclaordgenspeciesusersslum doesn't have that problem. You can see exactly what it means, and how far the goalposts are being moved. It stops creationists from letting the argument falling into one of definitions, which they seem to hate, and you can see exactly what they want to say.
Okay I'll be the first to admit that it doesn't roll off the tongue easily, but everybody knows that big words are sciency. Take pseudopseudohypoparathyroidism, for example, or pneumonoultramicroscopicsilicovolcanoconiosis, or even aequeosalinocalcalinoceraceoaluminosocupreovitriolic. All are long words and if you use them you will sound sciency. Why shouldn't phyclaordgenspeciesusersslum be able to join the ranks of sciency-sounding words?
So encourage creationists to use phyclaordgenspeciesusersslum. It makes our life easier to argue with them, and they can continue to use an appeal to authority by pretending to be science-type guys.
