i’m not trying to be mean so apologies if it sounds that way

Does anyone else find it extremely offensive when otherkin say that they are the deity tjat you work with/worship?

Then you need to block them and move on. It’s highly unlikely they’re the same being that you work with; though they would share a few traits as well as a name. Otherkinity is involuntary, and if someone’s existence offends you, that’s your problem and you need to take the steps to handle that on your own. If they’re demanding worship or something equally stupid, they’re either a troll or seriously misinformed. It’s not your job to educate them. Let someone in the otherkin community know and we’ll handle it.
