The older I get, the more I dislike people who are hardcore anything.
This includes religious zealots who don't like science because it makes them feel like that they believe in is wrong, but then go on to tell everyone who doesn't believe their trash that those people are wrong.
edit: I should add something to the topic. I am a geoscientist, and I'd want kids taught alternative concepts (as long as they could be scientifically tested or explained in a scientific way). Maybe that's too much to ask for SCIENCE class?
