I am writing this message from Japan.
Please answer my questions below.
1. You are deleting a large number of video clips posted by politically conservative Japanese contributors without strict consideration.
They have their own opinions and backgrounds. Isn't it too rude to delete them unilaterally, ignoring their value?
2. Don't you respect the freedom of speech of those contributors on this site?
Their clips were too easily judged and deleted. Do you have any rights to ignore the voices of their viewers who support their opinion? Your act is vandalism against the YouTube viewers.
3. Do you know that this deluge of claims comes from a widespread mischief with an unserious motive? You should not take up their claims seriously. They are just pranksters.
4. Would you make a similar act if you received such claims from people who stand on the politically opposite side of you?
Your answer should be made with many methods i.e. on YouTube's forum, on the official site, on twitter, and so on.
