I wholeheartedly agree with Chibi-Chan on the matter of whore being degrading to women. It is, and there's no way around it. Whatever is your intention doesn't get a pass on that, much like calling men pussies, little girls, bitches, so on—it's a sexist term used to put down women. People do often use those terms on men too and that's just part of the big problem actually. Why do men get called bitches and pussies and little girls when they show weakness or emotion or aren't good enough at subject x? All those terms have relation to being a woman, being a girl and the intention is to belittle girl/womanhood because being a woman is bad, women are weak and less than men. Same goes to the word whore.
Someone mentioned how "people are just offended easily geez!!!1" but that's
just not it. It isn't just us being easily offended, it isn't just us being special snowflakes, but these words
actually have negative consequences and a whole history behind them and actual effects on women and how women are generally viewed.
I'm taking an example which are rape jokes. Ironically, I hear the
exact same song "geez it's just a word/joke, I don't mean anything with it, you're easily offended you have no sense of humor!" whenever it's pointed out but with a little bit of googling you'll see it's actually studied and proven that rape jokes do decrease people's views on how serious rape is and increase the blame the victims face and so much more. It is how men (and women too of course; many women still live in the idea that they owe sex to their partners and pressured and manipulated into false consent is normal) normalize rape and sexual assault. Now rape jokes are much more serious than the term whore used but it's an extreme example I took to help you understand where we stand.
I think the whole "you're offended too easily" idea is because you've gotten used to all the offensive terms/jokes that when the people who it affects do finally speak up, you get pissed off because to you it's nothing and you can't get in the shoes of those who it actually hurts. It's not too long ago when I didn't think blackface was bad in any way but boy did I change my mind about that!
There's other terms you can use. Attention seeker isn't different from the intention you are using attention whore with, only one letter longer AND isn't degrading to women. How come is it that you are all so keen to grasp on the term 'whore'? I have my guesses honestly and it's got a lot to do with Chibi-Chan's point
The thing is whore, bitch, slut, etc. are STILL very much in use to describe women or prostitutes. It isn't a past thing like left-handed being evil or so. It still exists.
Some words are offensive and strong and they always will be. Changing the meaning doesn't do much. You don't go around yelling the N word and saying let's not ban that word, let's overly use it fuck those who are or have been physically attacked because of racism and the origin of that word!
