I'm not going to argue that it's appropriate (I think it is, but that's incredibly subjective), but how is it in any way toxic? She's owning the term in a way that empowers her; that's literally the opposite of toxicity.
Or perhaps gatekeeping and shaming vocabulary instead of reading for intent is the real toxicity?
Is it any wonder so many have issues when they turn every little thing into an issue?
You can choose to be offended by this or choose to view it with a sense of humor. That choice is up to you.
but she choose the title ... are you saying we should tell her what to write or what to call herself or what she should think?
Thinking is free, as is blogging. The line should be drawn at what is pushed into the HN newsfeed and up upvoted, which we have a shared responsibility to maintain for each other.
I don't think anyone should be policing anything ... except maybe some links that promote violence, abuse etc.
