Well that's the real question there, isn't it? Does the pervasive objectification of women in Japanese games affect how men view women in Japanese society?
simply put?no
objectify the other gender during "fantasies" is normal and it's done in every culture..again just look at the twilight series and how deep as a puddle are its male protagonists,usually defined just by how bad they want that "unique snowflake" that it's the female lead
that's fanservice for the female demographic
relationships are hard,especially for teenagers,objectifying the other sex makes everything simplier and thus the fantasy better
just look at how the usual movie romance goes..it stops at where usually the real problems arise,the beginning...every couple has it's "honeymoon" period at the beginning,and it's when time passes that problems arrive,it's those moments that you have to put effort to make a relationship work..and it's mostly the major part of a relationship..but when fantasizing about it,we decide to not consider that part,because we want only the good stuff in our fantasies
same here,it's a fantasy that avoids the problematic parts (aka,actually having to interact with a real human being with her own needs,problems,quirks)and goes straight for the appealintg part (aka the female,in this case virtual,body)
of course that's a generalization valid for only a part of the demographic..there are people who are totally able to have healthy relationships with the other gender and still like to see a pretty ass on the screen while playing..and again,that has nothing to do in how they perceive the opposite gender,that comes from their culture,what they were taught by family and society,their experiences,what their peers consider acceptable or not.
it's there that you need to intervene if you wanna change stuff,focusing on cemsoring panties on a videogame it's wasting a lot of effort for nothing when you could actually do something for the issue
