Trying to represent oneself in court is a pretty stupid thing to do, generally.

I am not a lawyer, I’m pretty you need to be able to defend yourself withing the legal system following all of its rules. You need to know the laws, their quirks, loopholes, etc. to construct your defense properly. Even if the case is complete nonsense, but you lack the knowledge to defend yourself, or the ability to use the knowledge you have coherently, you’ll loose.

A neat paper a filed in accordance with all the rules, a paper that quotes actual laws and precedents, will, generally, beats oral argument backed by common sense. And that’s in general! Let alone when you’re going against Disney and their nigh infinite army of lawyers.
