I think talking about this in your journal is a great start. Like you said, in everyones flist theres a lot of teenage girl that've been living vicariously through fandoms & they take what they "learn" there to their real life.
I personally dont like rape scenes even when there the role playing scene development, and when that scene is not there is a rape scene & there is no way around it. One of the biggest mistakes I've seen with fandom writers is that they assume the reader will get what they wrote hence why there is so much triggering content.
And I feel a bit of worry how easily other reader disregarded the need for a warning for triggering content. When someone writes you want & expect a reaction but not something that can be harmful to the reader.
Wow there so many things that worries me about this whole situation but I think you are at least sharing valuable information with your flist!!!

Awesome post!!!
