Theres a bug difference between being sexy and only being seen as sexy. Women may well put on revealing clothes, thus making themselves 'sexy', however she still has a brain and is a person and should be treated as such.
The word objectified means that this woman will be seen as nothing but a sex object. Hence inferring she is good for nothing besides sex. This is what women object to, not the actual thing of bein sexual.
And to the person above, kindly stop being a tit.
