Cosplaying is for fun, but if you’re really serious about it that’s okay too. Just don’t make others feel bad. You can judge someone on their costume, or on how well they fit the character, but you should never do that. And you especially shouldn’t say those thoughts out loud. If a cosplay is to be judged at all, it should be by the person who is wearing it, and on wether or not they are having fun.
When it comes down to it, elitists, we’re all just silly dorks in costumes, and yes, you are one of us. : )
