Is calling a girl "cute" offensive or demeaning?
Saw an article on Facebook a couple weeks ago (sorry, no longer can find the link), and a young 20-ish girl said she hated it when people called her "cute". She said it was demeaning because it starts her off a rung lower on the respect scale and makes her work harder just to reach the same respect level as others. Her story has stuck with me, though, and I find the question intriguing.
She did say she feels the same whether it's from men or women, and she does get it from both, though she wasn't as put off if it were from someone she has known for quite some time. Take from that what you will.
Personally, I would not say it to someone I don't know, but I will make a value judgment* based on looks just because I am a heterosexual guy and like attractive women. One's attractiveness being another's ugly, of course.
*- I do believe that ALL people make initial first impression snap judgments, on everything they encounter in life, including people, and anyone who claims not so is a liar.
