No, there isn't. "SJW" is an insult used by their opponents. (Some of them might choose to adopt it, but most as far as I know do not.)

> The definition of feminism has become sufficiently corrupted thanks to these people that women themselves are fighting against it.

I've seen that claim, but I'm extremely skeptical that it's a significant phenomenon.
