Original sentence: Arudou's tactics have been seen by some as unnecessarily confrontational with supporting research that is sometimes poorly substantiated, spurious or exaggerated in its claims
Edited sentence: Arudou's tactics have been seen by some racist Japanese as unnecessarily confrontational.His critics call him "non-cooperative" and a "publicity hound", but none admit that 1)Racism is prevalent in Japan, 2) If Arudou is successful in forcing laws to be inacted/changed, the new anti-descrimination laws will benefit EVERYONE currently unprotected in Japan.In fact, most Japanese, and a surprisingly number of misguided foreign passport holders residing in Japan oppose his efforts to expose blatant racism in Japan.They critique his research & data sources, but NONE of them address racism in Japan
