I think "aikibunny" has gotten to be like "blonde". It's a code word for "female". The presence of exceptions does not change this, only provides a weasling excuse for those who don't want to own their words. Perhaps the word should be retired from the discussion and another term found -- if, that is, a productive and civil discussion is what is wanted.
I disagree with your assertion. Historically it was and is often used disparagingly towards Ki Society-based training methods AND in our not so distant Aikiweb history was almost exclusively used to disparage a man posting very non-martial (and non-accurate!) techniques. Never have I ever seen it, heard it or used it as a gender-based term.
