Heyyy I think it's that time where it's important to discuss the nuanced conversation around DID/OSDD systems and taking accountability.
The kind of behaviors I'm going to discuss are more prevalent in faker communities. I've never seen an actually diagnosed system that's in therapy behave this way. If you find yourself being bothered by this, look inward.
And before I start this - a healthy reminder that your alters are fragments of yourself. It is your brain breaking off pieces of your individuality as a defense mechanism in response to trauma. You may have introjects of characters from media, literature, etc - but those introjects only stem as far as the basis of their formation - what connects them to your individuality as a person in regards to trauma. Your alters are still parts of you - they are still you.
Just like in almost every space online, there is an issue with grooming and abusive/predatory behavior. One thing I've noticed is that it gets swept under the rug a lot more in mental health communities, especially DID/OSDD spaces.
The common excuse being, "It wasn't me! It was my alter! I had no control over it!"
Like it or not, you as the "host" are still responsible. You will still be held accountable.
Your alters are still parts of you on the basis of trauma, and the excuse of "I groomed/sexually abused/physically abused another person because it was a trauma response" still does not apply or justify the act of such.
The court of law will not care about your alters either. You'll either get convicted or be forced to take an insanity plea, and having DID/OSDD does not make you "insane" - that's a stereotype that many real systems try and stray away from.
While it is true that there are differences in amnesia between DID and OSDD, as well as the amount of amnesia being somewhat of a spectrum depending on the individual who experiences it - amnesia is also not an excuse to evade accountability.
"I can't remember it!" Congratulations, you're still responsible if you hurt another person, and "not remembering" doesn't erase the hurt caused. Buck up and start making amends.
I hate to break this to you, but you can't fully separate yourself from your alters because alters are not individual beings. They are essentially fragments of yourself that have been compartmentalized.
Let's use Touya Todoroki from My Hero Academia as an example, an arsonist villain. A system may develop an introject of him based on a similarity around abandonment trauma (his childhood plotline) if the person was experiencing trauma around the same time they were consuming media of him - because remember - alters are formed based on trauma - DID/OSDD is trauma based.
Now, if that Touya alter started beating on people while fronting, the system doesn't get to use the excuse of, "Well, he's a villain!! It's not my fault he's hurting people!"
Because that alter was formed on the basis of a connection around abandonment trauma, not his villainous tendencies. Any kind of physically abusive habits "he" is displaying while fronting is simply because the "host" of the system shares that part - your alters are not fully individualized or independent. If your alters are abusive or pedatory, YOU are abusive or predatory.
This is why I always have to roll my eyes when people start talking about "source memories" that span beyond the alters reason for existing. That Touya alter isn't going to "remember" his little interactions with Hawks, Spinner, Shigaraki, none of that - because that isn't the reason for his existence - the reason for his existence being abandonment trauma that connects to the systems trauma. Everything else is just the system using their imagination.
You have to take accountability when you fuck up, it doesn't matter if you're a system or not. The people who believe that they can escape accountability for causing harm to others simply because, "my alter did it, not me," - and I say this with my whole chest, are not systems, and are only contributing to the harmful misinformation surrounding the debilitating disorder that is DID/OSDD.
