I didn't really like how they just kicked it out, and I don't think it was hurting anybody being a planet out there..

We shouldn't be unable to accept new things just because they've been that way for hundreds of years. I mean, we ALL know that the earth goes around the sun and the earth isn't flat, right? You'd better know that. X__x But when these were new theories, hundreds of years ago, people dismissed them. And they killed those guys for saying that stuff.
And they were RIGHT. It's silly now that people believed that stuff.
I know that Pluto isn't exactly something as important as the heliocentric theory. -BUT- What if it's important later? What if the people hundreds of years from now laugh at us for such a silly mistake? And there's no telling what might be important later and what won't be.
