Lets be honest, you can lump most if any fetish of this kind in a submisive or dominant side of preferance.
Say for example:
NTR - very popular here among some, but it is either submisive (MC being cucked) vs dominant (MC is doing the cucking)
Transformation - Same example, either the MC gets transformed (MC submisive) or MC does the transforming of others (MC dominant)
There loads of examples, but honestly, wether you agree or disagree doesnt matter, it's up to each individual to decide which end of the sub/dom side they prefer. Good example of a game that caters to both in the transformation/corruption genre would be "the Company", in it you can both be dominant and be transformed/corrupted yourself. It caters to both sides that way.
In the end, my message is: Dont hate on someone for taking a stance on either side, wether that be a developer or a player of a game, and wether they prefer dom or sub. Dont force your preferance on each other.
PS: this is not aimed at anyone specific, just a statement from my personal point of view. Even i myself sometimes voices my dislike for some feature or a other,but i try to always be suportive of those that dont share my tastes.
