The least hated princesses?

This list is pretty spot on. Mulan for sure gets the least hate, if ANY hate. I think Cinderella and Jasmine gets a bit more hate than Belle and Rapunzel though

I agree with this list a lot but I would have thought rapunzel got a lot more hate :L

Cinderella, in all honesty, but Rapunzel and Mulan are pretty close.
these three are pretty much the neutral club, with Cinderella in the lead. Few people love her, no one hates her. Rapunzel and Mulan do have their fan clubs, and when any princess gets lots of love there will be anti's ready with criticism. Mulan and Rapunzel do have their critics. (People say Mulan is a cardboard cutout, and that Rapunzel is a Mary-Sue). But I don't remember the last time someone had only bad things to say about Cinderella.
And may I just say you're spot on about Aurora, she /does/ get a lot of hate.

Tiana hated?? Where do you live? Everyone on the internet worships her. she gets no hate, at all, I have ever seen. at best she gets called a flat character (as she rather is, even though I like her).

1. Mulan/Belle tied (although Belle slightly more, however she gets a TON of defenders to make up for it)
2. Pocahontas
3. Tiana
4. Jasmine
5. Ariel
6. Rapunzel
7. Cinderella
8. Snow White
9. Aurora almost tied with Snow.

My list would be mostly entirely different from yours, to be honest. I'm not just talking about Fanpop, btw, just generally-speaking.

1. Mulan (No hate, really. Even people who aren't fans of her still respect her)
2. Tiana (Even though she doesn't get much love, she also doesn't get much hate either, in my experience. People are generally very neutral in regards to her. Many people who aren't really fans still respect her for how hardworking she is and think she's a good role model)
3. Belle (most people love/like her. she has some haters but not many)
4. Aurora (people are VERY neutral, generally. I really don't see much hate)
5. Rapunzel (I'm not sure with her, so I'll put her in the middle)
6. Pocahontas (a lot of people are pretty neutral - doesn't get much love, but not much hate either)
7. Jasmine (honestly I see a lot of negativity towards her, even though people love her too)
8. Ariel (loved A LOT, arguably the MOST-loved DP, but also has very vocal haters)
9. Cinderella (loved but hated at the same time - if people that aren't fans of DP want to bash the DPs they will often use Snow White/Cinderella as prime examples. Aurora is often forgotten about, hence why she's not as low down as these two)
10. Snow White (loved/hated at same time)
