>there's social justice terminology thrown around (safe space, expanded genders beyond gay/bi/trans, you get the picture) and the political conversations I've seen so far much more left leaning with no right leaning opinions at all . I'm not really going to judge them on that,

I think you have delivered a pretty good answer by yourself:
>"it's fine if they have there own little space, especially if otherwise they'd feel uncomfortable at some of the main sites (and or try to change their dynamic in an undesirable way)."

which I agree. Ideologies may be varied and if they want to stay away from any outsider zone, that´s fine. They create that space for themselves and just for themselves so threads don´t get derailed or too out of hand.

As a mod back there in Nextchan, I totally get why they implement certain rules for themselves in order to carry it properly. Understandable. Furthermore, we are talking about a forum, not an imageboard so that implies more order and rules by nature.

Now:
>The main thing that seems a little strange to me was the extremely restrictive rules of the booru.
here it comes the good part. Let´s check them.

>They have a no non canon shipping rule on their booru.
