<Snipped quote by Konica>
From my corner, and this is me being respectful about it; you are doing it for the sake of it, the sake of your storytelling. It is completely subjective if it's a necessary or quality change. I think it's superfluous. My reasoning behind why I don't really like it is mostly because it seems like a change that isn't a particular good one, I like comic books (even the ones I RP in) to reflect off the world and their politics which means laws that happen in my reality still happen in my fiction to have a degree of social awareness and commentary alongside a good story about fight against the thralls of criminal corruption. I don't mean to stray us into an argument because I respect your reason to do so even if I don't agree with it.
Let me rephrase: I'm not making changes for no reason. Its not like I just woke up one day and thought "what laws can I put back into this universe?". The reason I want to make this change is because of the following:
Batwoman is a soldier, and a large part of her motivation is the inability to serve in the military. Using don't ask don't tell kills two birds with one stone, since it also addresses her sexuality. Essentially, she can't do what she wants because of who she is. This is one of the huge challenges she faces and must overcome as a character.
If I used PTSD as the reason she was discharged (as you suggested), it wouldn't be the same. Her discharge would be justified, and she won't face the same discriminatory hurdle.
It sounds like the reason you object to this change is because of principal, rather than a specific issue that would detriment this RP or anyone's character. So I fail to see how, in a practical sense, this change would effect you or your character. Think of it this way: Are you really going to notice this change at all once we get started?
I don't want to be stubborn or a jerk, so if it really bothers you that much I'd gladly listen to any solutions or alternatives.
