Yes. Not a fan. You see it a lot in models I think. Fashion industry likes such feature on its women. I think that just one example of how the fashion industry caters to women and not so much to men.

I think it depends on the face shape. An angular jawline is just masculine like in the second picture but the girl in the first picture has a narrow defined jawline which is feminine and attractive. I don't think any of these guys here who mentioned that they like a non defined jawline know exactly what they're talking about, a weak jawline is a jawline which isn't fully developed > double chin and it looks like that the face and neck are one because there is no line just like with babies.
