I have nothing against Warrior cat role-players at all. I've read the books, I know the stories, and the cats themselves. The story itself is engaging and there is much adventure, action, and suspense. To first time readers, I highly recommend starting with the first book, Into the Wild. Or, if you are the lazy individual or have no access to a local library, simply watch video adaptations on Youtube.
As for the role-players, I can understand way most people would be skeptical and almost mean-spirited to them. From my perspective, most of the Warrior cat role-players I would meet either never read the book and just like the theme of Warriors. Those that have read the book are usually neglectful of important points of the story, namely the warrior code, how the leader obtains their nine lives, and resurrecting dead cats, like Bluestar. Just to clarify, I really like like Bluestar, she was wise, took risks, and made sacrifices, namely her life. However, when I see someone role-playing with characters such as Bluestar, the leader of Thunderclan, with so little respect and dignity, it bothers me.
Another thing with this, as maintained before, is the power-play and god modding reputation. I've encountered a good number of Warrior cat groups that do this to no end. Because I didn't want simply draw conclusions, I decided to approach a clan with one of my canine characters. Once I posted, I had an alright experience. I was soon greeted by a kit and its mentor. I'll give credit, this I liked because the mentor was with the kit at all times. Also I liked how mentor encountered me as the stranger animal I was, interacting with their enviroment. We role-played for a while, a good hour or so until they had to leave. And for those wondering, no, this was not a commercial clan, it was one those made-up ones, like Swampclan or Earthclan.
In closing, I do not essentially hate any theme of role-play, particularly the ones influenced by the Warrior series. As long as the book, the story, the idea, and the characters (if you role-play as them) are respected, then I have no mind. In addition to respecting those around you and role-playing in an appropriate way, then no worries for your clan being set into the norm of those who don't.
