If your claim is regarding objective reality and you want to convince me of a point about it, then sure, you'll need evidence.
If your claim is about an abstraction, it is not susceptible to evidence.
If your claim is about your feelings, I'll compare it to your behavior (which is, after all, evidence of your feelings, oftentimes), and make a determination then.
