Nice post :)
My main argument, as a biologist, when I hear hate about homosexuality being unnatural is exactly that, to tell them Nature thinks otherwise...
Sometimes it shuts them up, sometimes I actually have to dig around for publications and such to prove it to them (though, of course, they often nod and then go right back to hating... no correcting some people, sadly XS)
Proof is rather irrelevant when it comes to beliefs.
True...
The sad thing us that that even applies to us scientists.
Given the lack of guarantee of thousands of years of time, Ive still nit trued to validate...well... anything school has taught me about biology (which didn't come with experiments).
I hope that when we get to brain augmentation technology, we'll create a device that allows one to bypass some of all those shortcuts the brain likes taking.
Course, then the brain would be an even bigger energy hog than it already is, and wed be consuming tons more food XS
