Actually, you're right about one thing. It's better to do away with politics entirely. I'll go ahead and fix that.
I'm going to assume that you don't actually think Uboachan should be a platform for literal naziism. I'll also give you the benefit of the doubt and assume that you don't think that sexism, racism, homophobia, or transphobia are legitimate political positions, because you weren't very specific about which part you took issue with.
Where those things are discussed or joked about, people will appear who promulgate all of the above. Before I let this place go to shit, we had lots of female members and transgender content creators. Most of those users left a long time ago, because people who support the things I mentioned made them feel unwelcome. This was supposed to be a Yume Nikki fansite, a content creator and indie gamer hangout, and a NEET support group, not a burning racist clown car.
You say it's about politics, but why should I allow people to promote the ideology that is trying to take away my friends' and partners' right to live freely? That person wants trans people dead. He hates blacks and mexicans. He's a confirmed rapist and misogynist. Those aren't political opinions. So it's not about politics for me, it's about everyone feeling safe, and speaking openly about Yume Nikki, indie games, content creation, and their personal problems
without getting shit on. I don't actually believe that banning these things will make you feel unsafe, but keeping them around will make a lot of people feel unsafe. If Biden or Obama or even Bernie Sanders did those things (and Biden did some of them!) I wouldn't want their images in a space I want to be safe for those groups of people either.
So why did I allow it all for so long? Because years on 4chan and 4chon addled my brain and made me value free speech over freedom itself. I realized that I was embarrassed to invite friends here, that I was ashamed to be the owner of what could have been and once was a flourishing Yume Nikki fansite, content creator, and indie gamer hangout, before I fucked it all up by letting people like I once was chase out so many of the users who added value to this community. I was afraid that anyone I invited here would be chased out too, or would think less of me for running the place. You shouldn't need to have a thick skin to be a fan of Yume Nikki. Our reputation is trashed, the mods have left because I prevented them from doing their jobs, my own partner who was once a prolific game creator on this site is afraid to be here. I'm tired of ignoring the problem.
So, nah. I'm not rolling it back, but I'll take your suggestion and ban political discussion and imagery completely. (Not really sure what counts as leftist imagery though. Karl Marx or something? Bernie Sanders? Sure, they're banned too.)
And yes, Uboachan now is and ought to be a safe space. Deal with it.
