Firstly, I am against watching: streaming or downloading, fansubs. If you want to watch a series before its north American release import the japan releases at least. That way, in my mind, you have obtained the license to the episodes you've bought, and re free to watch all the subs you want. There is so many quality English dubs, that wanting to watch Japanese releases is often just an excuse not to show the dedication. When a top series is released in Japan and the American release seems far off people then tend to somehow see themselves as actually caring about anime, despite the fact they show no dedication, care or regards to the production of that anime and watch it anyhow. Death Note is a current top example of this. Of course, wanting to watch a retro Japanese only release, following the 10 year abandonation policy, does not cause the same lack of support to the makers as, as many people did, watching all of Naruto to date (or stopping at fillers), without buying a single Japanese or North American release, i would hope anyone would see the damage in this. Some may counter this with the poor quality of the dub, but watching the subs initially obilgated yourself into purchasing something. If you want a Japanese kendama, Russian alcohol, etc you import it. Anime should be no different.
Again: Watching anime, whether be it though downloading or streaming, without any support going to the creators shows that you do not truly care about, like, or respect anime or the industry.
Of course, downloading dubbed anime which has been licensed is more accepted as its truth: anti-otaku. You cannot truly have the slightest care for something if you show this much disregard and lack od morality, however this Tabu does manage to creep through. This is a much more blatant strike against those who do care for anime.
In conclusion, piracy is piracy, and if one claims to have any care or interst in anime they wouldn't do what they do. As people claim to have financial difficulties, they fail to realize that the cheapest economy boxsets can be gotten for no less than 40$. Whole series' do not have to be purchased at once: singles can be picked up for a bargain at our friends at RightStuf, and even a volume a week would be a start in showing that you do care about anime.
So pick up a DVD, read a Manga, or check your TV listings for some anime love!
