Am I antiship or proship if I don't give a shit if people are writing things about noncon/incest/pedo but don't want that near me? Like I'm extremely uncomfortable *reading* those and would prefer people who post about that not to interact, but I get that fiction is the best way to explore dark topics. What does that make me??
That is 100% on the proship side of the slider. Like no one says you have to like or want to consume the media (and if they do they're a red flag) in order to defend the right for it to exist.
The system has various things they personally will not consume. Some of it is contradictory; Ares for example won't read anything that contains minors in sexual situations at all while the rest of us have a cutoff age of age of consent (16+) in media that places those older teens in life or death situations.
It's not that Ares doesn't like some minor characters in concept, it's just that he'll only read aged up fics of them because of what he enjoys. He also doesn't give a shit that the rest of us read what we read. There are several other examples of this, I'm just using the most sfw one.
If Ares was a singlet, he wouldn't have "read" any of those fics at all is what I'm getting at, putting him in the same situation as you, and with a topic a lot of proshippers don't have an issue with. And there's nothing wrong with that, just like there's nothing wrong with you wanting to avoid topics that make you uncomfortable.
Being truly proship is being anti-censorship. You are talking about being anti-censorship and just applying the fandom discourse labels to it. You can avoid them entirely and just call yourself anti-censorship instead. It's what we do.
You also do not have to be part of the proship community even if you fit the label. This is something I see people struggling with a lot; that falling under the label makes you part of the community - it doesn't. Being part of the community is an active choice. Just doing your thing quietly while fitting the criteria makes you "proship" in the sense that you check off the boxes, not that you're automatically us vs them. This shit is opt-in, not opt-out. The section of the pinned post has to do with fitting the label itself, not being part of everything.
