Yes the Bill COULD affect [insert some anime title which OBVIOUSLY WON'T be affected], but I very much doubt it will. This fear here is based on an article but nobody has read the actual system of classification. Go find it; it's most probably going to be available at request, like all ratings schema. Most likely, you'll find that like EVERY ratings schema in the developed, FREE world, there are multiple means there in which honest artistic expression CANNOT be suppressed, but malicious or devious works CAN BE.
Only the USA is the USA. It seems that most people today think that their own country's rights are just like the USA. This is the result of basing all their common knowledge on imported media and opinion. So called "freedom of speech" is grossly abused and distorted in the USA, but so be it. In other countries, there are limits when such freedom is at the detriment of others, especially others less powerful.
Egalitarian positions such as those in the USA's freedoms of speech and expression, etc, are brilliant in theory. They offer protection to poeple suffering cases of REAL oppression and subjugation. However, they also lead people down a slippery slope where in their drive for egalitarian utopia, they ironically harm the people around them.
Anyway, even with my love of anime, I find it hard to defend the products that this Bill is going for, and it's not the Evangelions or "transforming heroes" anime which are so popular. Arguing that it IS, is only clouding a very real issue of child objectification for sexual purposes. Any body who doesn't live here in Japan is also deficit in understanding of this Bill's context. When capsule toy stores have entire rows dedicated to figures of underage girl characters in post-rape disarray, or beckoning seductively, that's a problem. Those figures are from and fueled by the sexualisation of children or "child-like" bodies in comics and anime.
This serious issue needs to be addressed, but perhaps this Bill is not the best way to go about that. Yet, it's a start in the process. Otherwise, defeat it and introduce a better means. It seems that people today are so "yes/no" in their thinking, all or nothing. There's no sense throwing the baby away with the bath water.
