No, I know we can all say this persons beautifull and that person. If every person was beautiful that the word loses all its meaning because there is no reason to even say it if everyone is beautifull.
just as in the animal kingdom, some animals are beautiful to look at and some not so. people are no different, some are beautiful(although obviously people are differing on who) and some have been beaten with an ugly stick.
Personality plays into looks for me. I know you said no personality but it really does play into looks. Someone can go from unattractive to beautiful just by how they are. I have only met a couple ugly people in my life, they were the meanest ugliest girls you will ever meet. (luckily you don't have to) Not everyone is beautiful, but no one is ugly unless they are ugly on the inside.
No, because I think that saying stems from the beauty in each persons individuality, not necessarily their looks. Of course not everyone is beautiful to every person in the world, because everyone has different tastes. But, I DO believe that beauty is in the eye of the beholder, that's a whole other quote to get into though haha.
Obviously not everyone will be physically appealing, but the idea of beauty will be different from person to person. So what is beautiful physically to one person could be ugly to another. I would say that "everyone is beautiful to someone" intead of just "everyone is beautiful".
