Allow me to quote from the Japanese constitution
Article 21. Freedom of assembly and association as well as speech, press and all other forms of expression are guaranteed.
No censorship shall be maintained, nor shall the secrecy of any means of communication be violated.
Though some would argue differently, here and the US both do seem in my eyes to be examples of “civilized society”.
Whereas I’m no great fan of the Wermacht cosplay types I sometimes encounter here (shown in this old post) I understand the legality and more so the reality of the situation that though I feel offense, I am not being endangered in any way.
