I Prefer Victorian Semantics

OK guys, lets gets our maturity hats on (maturity pants will also be permitted).
I think we need to sit down, and have a bit of a chat about semantics. I know that normally we don't talk about 'serious things' here, BUT TOUGH, IT'S MY BLOG, I'LL TALK SERIOUS IF I WANT TO.
Phew.
So, what I think we need to talk about, is the word 'slut'. Or 'slag', or 'tart', if you're a mustachioed gent from the eighteen hundreds.
I don't often use the word 'slut', and it's not a particularly common term among my social circle. This may or may not be because I hang out with a lot of very left-wing, shy, English language students. So, I looked it up (I Googled it) and was presented with this:


Slut  
Noun
Slut is a term applied to an individual who is considered to have loose sexual morals or who is sexually promiscuous.
Synonyms
trollop - strumpet - harlot

Bless you Google for your synonyms, you sweetheart. 
Let me give you a quick background check on this post: one of our friends recently got  new girlfriend, and as soon as we found out, one of the phrases that I heard being thrown around a  lot was "Ew, her? But she's such a slut!"
And to this I say:
Big deal.
Is it honestly any of our business how many people this girl has slept with? I'm in an age group where people have finally realized that the word 'dyke' is unacceptable, and I think the word 'slut' really needs to go the same way. It's still judging people on their sexuality, whether it be who they sleep with, or how often. I don't know if it's still a word only applied to women; I know I've heard plenty of men being called sluts as well, but I don't think it's a title that any gender deserves to carry.
I'm not about to turn into a massive hippy who thinks that they identify as 'otherkin' (I Googled that as well), but I'd rather not go around needlessly offending anyone based on a random judgment of their personal behavior. In the words of Stephen Fry, be adorable to each other.
That will be all.
Thankyou, and goodnight.
