Hi Buddika,
I think being unable to define 'kind' is one of the lesser problems for a creationist. Look at what else they have to blindly accept, the whole flood episode must be a total nightmare for anyone with an IQ over 10 to defend. The many different translations of the Bible and its many contradictions and impossibilities are ignored by creationists. The fact that EVERY dating technique supports a very old earth, well relatively old compared to Bible chronology, doesn't mean a thing to these guys.
Morons like Kent Hovind, Ken Ham, Henry Morris, Ron Wyatt and Carl Baugh get validation from eager xians who cannot be bothered to get off their butts and do some real studying. Do you really think that being unable to define 'kind' will make the slightest bit of difference to these people?
These people live in a different world from me and you, they live in a fantasy world where unicorns play, a man can kill a thousand men with a bone, men can live inside whales for days, and 1+1+1=1.
These people, the Hovinds and the Wyatts, are psychologically unsound, there's no other conclusion to make. We all know enough about Hovind to know that if he lived in the UK he would be sectioned under the mental health act by now. I do think though that people are starting to realise that Hovind is brain dead and are starting to believe that his 'scholarship' is embarrassing.
Anyway, keep up the good work, if enough people can get together and expose these morons for what they are then maybe the world will be a safer place for us normal folks.
