Err...
Are people seriously defending 2ch as some kind of harmless « Japanese anime forum »?
2ch has been for years the main breeding ground for those known as « Neto-uyo » (ネット右翼, local equivalent of the alt-right).
The political forums there are a monstrous hive of conservatism, nationalism, exceptionalism, revisionism, and racism in proportions rarely seen abroad with that level of visibility. Luckily for the entire world and especially for the Japanese youth, it's been restricted and even censored at provider level for years.
Even on completely mundane topics, I dare any single one of you to find a single thread there about, say, a smartphone, without anyone mentioning how shittily it was made simply because it wasn't Made in Japan.
Racism is deep rooted in Japan although unfortunately most of it remains unseen to many native English speakers who, honestly, only see very restrained and specific aspects of the society that they then propagate as the absolute truth - when in fact they were lead to encounter solely certain types of people who always serve the same exact discourse.
Oblivious poor foreigners gobble it with an apparent pleasure as it feeds the image they wanted to reinforce of the country, but never get deep rooted enough that they can start actually living in the country, they just keep on sliding in the surface. They stay as colonists, not as citizens.
They are clueless.
Everything you see on YouTube from "Japanese speaking" white youtubers is complete crap.Not a single one of those people could do even a simple serious translation job without fucking up at every corner. I know professional translator who still do a lot of fucking up.
And these are considered "experts".
