I'm not going to defend her as a person, I'm happy with people not liking her for all sorts of reasons, but calling her not attractive is bizarre. It's the sort of thing that a teenage girl sees and gets insecurities about, because "if she doesn't qualify as attractive then I must be hideous".
Honestly my appreciation of beauty got much better when I realised I was unconsciously judging everyone by every little flaw they had because I had picked up this judgemental devil on my shoulder that was ready to laugh at me if I found the wrong sort of person attractive. I changed my attitude from "where are their flaws?" to "what is their unique beauty?" and suddenly the world was full of beautiful people that I had never noticed before.
And when I get to know someone, the more familiar I get with them and the more I care about them, the more their apparent "flaws" become unique quirks of their beauty that I like.
Personally I have spent very little time looking at or thinking about Taylor Swift, but if you are curious to understand why people might find her attractive, I just did a search for "taylor swift pretty" and I can tell you it wouldn't be difficult to explain it. Let me know.
To me it’s because she has a rat face and a plain Jane flat body with no curves. I just find her hair style and everything about her looks unappealing and boring.
It has nothing to do with her as a person or her personality.
I am not a fan of Jennifer Lopez or her music but she is at least physically attractive. She has a good looking body and face with some curves which I find attractive.
I am happy for you that you think she is attractive. I do not find her attractive at all. At best she’s extraordinarily average and no sex appeal what so ever.
