Why are people getting so deeply philosophical about the human psyche and the phycology of society in a gag comedy about a girl who's horny 24/7 and her prim and proper future wife???
I'm pretty sure there are some manga out there that actually touch on those subjects in a serious way and sometimes in a philosophical and/or introspective way.
I'm not saying it's wrong, just that it's like you want to talk Star Trek so you went to a Star Wars convention, some people there will be willing to converse about the subject but that's not why they're there. If you go to a Star Trek convention you will get infinitely more engagement and conversation since everyone there is there for that exact reason.
Time and place, both are important in their own ways, together and individually.
