Sort of. I think you really have to evaluate things on an individual basis though. Also it's important to note that we're talking about fantasy here - there's no real people who are being objectified. Yes, in human history it's sickening that women have been forced into sexual acts and treated as nothing more than objects of mens' enjoyment for years. But this isn't human history, it's fandom where none of the character are real and, thus, no one is getting hurt. Personally I don't think it's "bad" to objectify anyone in that context, if that's what you want to do, and whether you have a bad attitude about it is about the individual, not the sex of the person they happen to like objectifying.
