Like all media, there are good and bad examples.
Now from what I have seen, the bad does indeed outweigh the good, but that applies to music, movies, books and classical "art" as far as I am concerned.
For every 20 throw-away films or crappy series that embody one or all of the criticisms you have highlighted above, there are one or two genuinely special, moving, unique, funny and entertaining examples.
Bear in mind also that many of the tropes you highlight as negative, offensive or just plain stupid are native to a very different culture to ours - clearly non-Japanese audiences may well find it difficult to identify with or appreciate certain aspects, if not
all of it.
Personally I have no time at all for Indian music or Bollywood movies or indeed Arabic entertainment in any form I have seen it in, but I would be foolish indeed to dismiss it
all as somehow unworthy, offensive or of quantifiably less value that the art that I
do appreciate, given that I either don't understand or can't/won't identify with it.
Don't like it? Fine!
To dismiss the
entire body of work in a lazy generalisation of certain (hysterically over-publicised) aspects present in some examples of the genre is a bit daft.
Mind you, TBF Shippy doesn't always help the case...though in his defence he does tend to parody and play up his obsession in a manner to which critics like yourself seem to expect and often react to...
