I am willing to change my mind on this, but my current thinking is that I judge any men who use sex dolls like this, as that's what they think about women. And yes, sex dolls aren't women, but we as humans anthropomorphise anything, given the slightest opportunity. Look at the Pixar lamp, ffs! I don't believe for a second that the men using these dolls don't invest some feeling into them, see them as they see women.
I'm all for men using things like fleshlights, if they want to, as they are a mechanism, not 3D porn. (I remember a Sunday magazine supplement with a "what are you packing" holiday feature, and an aid worker who had his kit photographed was excoriated for having a fleshlight with the rest of his kit, and I remember thinking "good on him for having it, at least he won't be abusing local women...")
