The difference is, my posts and discussions are there for you to see. I have no control over what you post.
The difference is you expect of others what you refuse to do yourself. It's not my responsibility to search for proof of a claim you made. It's yours. If you refuse that request, don't make requests of me because I don't take them from cowards that get their panties in a wad when someone says something they don't like or in a manner which hurts their feelings.
To answer your request, "I have no obligation . . . to an asshole". What the fuck are you going to do about it? Talk big some more.
