The method to get there is the part that defines it, though. Suppose we were looking at a bunch of different games that all end up with the girl becoming the protagonist's slave. If one of them gets there by abusing and degrading her until she gives in, one of them gets there by hypnotizing her to love it, and one of them gets there by changing her memories so she thinks she was born into slavery, those are three different fetishes.
You may like more than one of the fetishes we're talking about, which is why you don't make as much of a distinction, but as someone who hates one and loves the other, trust me when I say they're two different things that appeal to different types of people. Snow Daze is almost completely devoid of the things I don't like about common sense manipulation, and I know a lot of people who are fans of those specific aspects that I dislike who weren't interested in that game.
If I'm remembering correctly, they don't accept it as "normal" until the ending, and even that's not "she's always been a puppy" so much as "wow, she really enjoys her puppy play, I'm glad she's having fun". Prior to that, it's just something they play with behind closed doors.
Additionally, they still don't treat these things as normal for everyone, they just choose to live an alternative lifestyle. That's another key difference, since it's not their "common sense" that's changing, just their personal lives. I recall them specifically talking about how different their lives have become in the harem ending.
if i'm being honest, the aspect of mind control I enjoy the most is where there sense of normality is altered, in any aspect, in any way, with any method involved. it could be subtle, it could be obvious. it could be one person, or the entire world. so long as it involves someone doing something they wouldn't normally do, caused by mind control, it's good enough for me XD
what i'm saying is that if normal is altered as a result from mind control or hypnosis, that's all that matters to me personally. I am well aware that there are differences for sure. for instance, the examples you provided, I don't enjoy any of those, i'd much prefer if she was hypnotized to think being his slave is just normal, or her memories altered not to believe she was born into slavery, but instead that this was always normal...does that makes sense?
i'm saying I enjoy normality change in the broadest of senses, it could be actual common sense alteration, it could be universal acceptance, it could be just being ignored no matter what, it could be memory alteration. so long as what is normal is changed in some way, shape or form, i'm happy with it.
however, I respect your outlook on the matter, you bring up very valid points, and, if you'll indulge me, could you perhaps go into detail on what aspects you love, and which you hate? perhaps a reason why? i'd love a different perspective on the matter other then my own, and it would greatly help me differentiate the different forms of "normal" mind control/hypnosis (for a broad term)
