No, I think we're just not using the same definitions for homophobic beliefs. I don't mean outright hating other queer people, but buying into homophobic/sexist ideology on some level. That said, it's very common for people to not be conscious that they have drunk the kool aid.
Honestly, this is getting way too technical for an off-topic manga discussion, but just for reference, and in one last attempt to clear up this misunderstanding, this is a better definition for internalization by Lev Vygotsky:
- An operation that initially represents an external activity is reconstructed and begins to occur internally
- An interpersonal process is transformed into an intrapersonal one.
So all it really takes is for an interpersonal process, such as someone saying, "Gay people shouldn't kiss in public because it's gross" to your face, to becoming an internal process, a voice in your mind saying, "If we kiss in public, people will find that gross." It does not necessitate the acceptance of the value behind the norm. One could believe the attitude to be morally, factually, or pragmatically wrong, but as long as the reaction has gone from an external one to an internal one, internalization has happened. So, internalized homophobia is simply the internalization of norms originating from homophobic values. It, once again, does not necessitate the acceptance or justification of those values.
