The Japanese are a bit different when it comes to Nazi imagery, it seems they don't mean anything by it: they just aren't taught about the second world war properly.
I would say 'at least it's a peace sign' but, you know, so was the swastika before someone put it in a white circle on a red background and marched into Poland...
there is absolutely nothing that could excuse op for sharing such openly fascist symbolism, the same goes for you and your defense of his actions. the japanese committed unimaginable crimes, just like the germans, e.g. through unit 731. and no, the symbol on the flag is not a "peace sign" but a yr rune used by the ukronazi "misanthropic division" among others. the picture was probably drawn by some pasty ass weeb anyways, a demographic that is for some reason even more fascist than the rest of westerners.
There's a newer article on the website about this person getting booted(?) off Privex because one of their business partners found Privex's response to this writer objectionable. Here is the other article. From just what this person chose to post, it seems they host loli/shota content (drawings). Uurg.
(I did not do any further research than skim the articles he put on his site).
The research itself is... a nice resource. But... if you thought the image the blog writer chose for his article was a red flag, your instincts were good.
From what I could tell by reading the article and some posts on Disabled's social media, Privex was pressured by a business partner to kick him out, but they didn't bend the knee.
Honestly good on them for standing up for their principles.
