Is there some reason you expect anyone to try to prove or disprove your bald assertions? This type of reasoning is called argumentum ad ignorantiam, or argument from ignorance. When you boldly assert 'x', then provide no proof, then subsequently expect others to disprove your assertion, you expose the weakness of your own argument.

It is not our responsibility to prove or disprove your assertions. If you have enlightening information to share with the class which you can cite, then please, by all means do. Otherwise, get thee gone.
