Why are anime fans against buying anime?

Out of all the hobbies and fandom out there, anime fans are some of the most backwards people I know. It's the only fandom I can think of where it's members actually encourage each other NOT to support the very thing they love. Why is that?

Because the Japanese anime industry is a shameless ripoff meant for socially retarded otaku and the North American anime industry is a half-assed piece of shit that markets itself exclusively to the stupidest parts of the fanbase.
