Women are terrible judges of other women's hotness, because (unless you're a lesbo) you never try to fvck them.
That's also why you girls all say you have "beautiful, intelligent and delightful" girl friends, while in reality they're completely average or even homely / fat.
Isabella isn't the hottest thing I've seen, but she's attractive and definitely above average.
Vice versa, it's also true - men are terrible judges of how attractive other men are to women, for the same reason stated above.
This isn't one of those things your feminist teacher tells you at school "there's no right or wrong, dear, just tell us your opinion". You have the right to having an opinion, not the right to have it unchallenged.
I'm also enjoying being the only man defending a woman's attractiveness while other women slam her for being average. Isn't it usually the other way around? What happened to the sisterhood?
