If we don't teach creation in school, because of other people's beliefs, why teach evolution?

I don't really believe in creation (or evolution), but it just saddens me how people bash on creationists, and don't let them learn creation in school, while it's okay to teach them the [i]theory[/i] of evolution.

I see this as bullshit.

Both sides have no proof that either creation happened nor evolution (thus the [i]theory[/i] of evolution). In my opinion, we should just leave both out completely (or give students an option).

It's not fair to creationists to not be able to learn their beliefs, while other beliefs are forced down their throats. It's just not fair in my opinion.

What do you guys think (and yes, I did get this idea from another person's post about wanting to fight a creationist on their beliefs)?
