Since when does using uppity to describe yourself constitute self martyrdom?
Martyr complex, not self martyrdom. There's a difference. Then again, perhaps "hero complex" would be a better descriptor. Eh, I'm sure you get the idea.
To answer your question; the word itself? Not necessarily. In the context of portraying yourself as an oppressed minority fighting for equality and justice when in reality you're simply arguing on the internet? Very much so. The fact that Ms bin Bambi actually describes it as "reclaiming words" just says it all, really.
