Tabatha's Bitch Takeover

So, today I was browsing Google News as I usually do and this headline popped up: "Tabatha Coffey: The making of BITCH"   in which Ms. Coffey equates "BITCH" to being honest and willing to speak her mind.  I don't have a problem with being honest or being willing to speak my mind...sometimes to my own detriment.  But why should that require me to be called a derogatory term like "Bitch".  Why can't I be just  a woman and not a bitch?
