Same thing happened to me. I realized it was trek memes. Didn’t understand the relevance of Risa. Googled on memory alpha and found out. Had a good laugh at the joke as it were. Understood why there was no written out explanation of the naming. It’s part of the spirit and injokeness of the place.

The reason people are antagonistic is because it’s all coming across a bit entitled.

It’s just trek memes. Chill. You’re going to be ok man.
