Part of the problem with ignorance is that having anything to so with animals, except for a couple of exceptions, is considered a bit suspect by the majoprity oe people. The exceptions are farmers (an most people don't think about where their piece of beef has come from), pets, especially dogs and cats, and horses (mostly for racing).
Just think of that very derogatory title, twitchers, for people who enjoy watching wild birds. Mention that you enjoy going to a zoo (and without children) and what sort of look do you get. Say that you keep birds in aviaries, rather than just an odd budgie, and people will regard you as somewhat strange. Show any real knowledge about animals and you are regarded as somewhat a nerd. Even children who are knowledgable about animals are teased (I'm sure that Hornbill has suffered from that somwehat).
This leads to a strange dictonomy in our attitude about animals. Most people only know what they have absorbed thropugh their childhood (eg through ABC books, docos that they were forced to watch at school etc) and never build on that. The only real exposure is through movies such as the recent spate of penguin movies, where the animals are so anthromorphised it isn't funny. They anthromorphise animals because that is all that know. It becomes even worse when people bring God into it.
I know people who are so petrified of animals that they will run away from a chicken ( and no not a rooster on the warpath). This is because they are so citified that they have had no contact at all with animals.
This then leads to the problem with animal rights people who have no real knowledge of the cute and furry, of what animals need or the importance of species, ecosystems over individual animals. An article in the latest Bulletin magazine highlights this when Cohen, a former enviromental minister writes about confronting an animal lib. over kangaroo shooting. The animal lib. didn't even know that there were more than 5 species in the macrapod family. That the big five (red, two greys, wallaroo and euro) each number in their millions etc. He was just worried about something cute and furry being killed.
People who are generally ighnorant about animals then swallow the animal libs arguements whole and don't bother to research the facts. Most stupid people aren't really stupid, they are just lazy and arrogent.
