I think, ultimately, you will see poor work produced by any type of person with any type of camera. Whether the work is intrusive, of poor taste, of poor technical execution or objectifying, like others have said, is the realm of highly subjective interpretation (the photo of the woman in burka shopping at a lingerie store posted on the forum recently and the discussion that ensued comes to mind).
The thing is, I think this is an incredibly diversified community, with photography as its centerpiece. You have exposure to material from guys with big view cameras, all the way to mobile phone photographers and every sort of combination/variation in between. Bottom line is, the community is a passionate one, and the discussion of gear, the classifieds, the gallery, all achieve a common result: the stimulation of a craft that is constantly shaped, influenced, and re-oriented by the realities of market and technologies.
I feel what you raise is not necessarily direct objectification, but simply the experimentation of vision that this whole diversity of discussion generates. Like anything in life, there will be a vast mass of material, produced by a collective of passionate professionals, hobbyists, and curious individuals, and out of this collective you will see more than a few excellent photographs - from photographers old and new.
The rangefinder community is a lively one, maybe we're all "hipsters", maybe not, depends on who's talking. The work of the site's administrators, the vast volume of resources provided by the contributors, and the criticisms of butt shots, back of head shots, and blurry shots, are all part of this niche. It's good to see this type of discussion because it leads to self-questioning and debate. That's the whole point, isn't it?
Anyone with a camera can make a "bad" picture, but what is "bad"?
Maybe Moriyama's blurry shots? How about Winogrand's women? Maybe Bruce Gilden's expressive and surprised faces?
Having a rangefinder does not simply give you the licence to make "bad" pictures, it gives you a licence to take photographs, and that's a good thing.
Cheers,
