Imo a lot of BSD discussions are very optionated and not productive. A lot of people take two extreme sides and debate about that instead of coming to see other's perspective. My thoughts on BSD have changed so much since I started watching it because I let other people's ideas and perspectives change my own. You should always welcome and challenge new ideas to make them more complex.
For ex; "Dazai is evil and abused Akutagawa, he is the worst and should die" as well as "Dazai did nothing bad, everything is Mori's fault and he is a good person" can be two opinions, but NO ONE will reach common ground to the more complex answer "Dazai was a teenager when he committed those crimes, he should repent for what he did but also deserves a chance to grow and change" (I can confirm this, in both Reddit and Tumblr I didn't get much reaction when I made posts about Dazai's misunderstood character, not as much as I hoped at least)
Shipping discussions are on next level toxic, because of which I stopped being in that discourse. If I see anyone say "sskk are platonic" I won't get mad, cuz yeah, sometimes I also see them that way too. Why should I care what anyone else thinks about a ship I like. Skk's being hit with a lot of hate recently, which I completely understand considering what Asagiri said about them, but that doesn't mean people would stop shipping them. It is still the most popular pairing and what brought a lot of fans to bsd itself.
I stopped writing long posts about shipping, because no matter what I would say, someone will pick a bone with it. It's better to just make cute posts and jokes in your safe small community.
This is a fictional story. As a writer myself, I believe interpretation is the most important part of literature (NEVER takes things at face value, if you think a piece of literature is open to different interpretations, that means the writer intended it to be!); I don't care what I wrote, I would prefer it if people were able to make different interpretations of my writings. Bsd has a bunch of people with different opinions, but there is a lot of misinformation, mischaracterisation and toxicity that ends up killing these discussions.
Headcanons are valid, but not everyone will agree with them. The ships you like, might look like siblings to others. Your favourite character might get misunderstood or overshadowed. Yes, not everything has to be skk, but it is very hard to stop doing that when a lot of fans came to bsd for skk, you can't kill a fanbase overnight. (Ps: if you really hate a specific ship, block the tags! Don't call out the fans of said ship and go to war!!!)
I have always been Switzerland (neutral) in most discussions all my life, so maybe only I feel like this-------🤷🏻♀️🤷🏻♀️🤷🏻♀️🤷🏻♀️
Nuanced opinions are always the best ones. Having extreme opinions and pushing them as truth to everyone else is not what BSD is about.
We have so many complex, grey, imperfect, deeply psychological characters, why should we see them as perfect angels or devils when they are neither?
