The first part lost me but you’re mad that the word slut exists and that at some point someone called you a slut and you’re talking to me because I agree with you that slut is a derogatory term. 

Right there is the problem with your logic.  I don’t have a problem with girls\people being open with their bodies.  A LOT of my Tumblr is about even bigger people showing off and being proud but it’s specifically SLUT SHAMING I pick on.  Who’s offended by that?  Sluts?  Who would decide to call themselves a SLUT and then be offended when they get shamed for it?  It’s only when someone steps forward and declares themselves a SLUT that anyone can be offended for ‘slut shaming’.  At that point it’s them being a slut and they probably should be shamed if for nothing else but self identifying as not a free spirit or open person but a SLUT.  You seem to HATE the word slut, it’s not one that works well in a positive way and nor should it. (P.S. there was more than ‘like your blog)
