You need to prove you know this is wrong! *No, I don't.*

Concern trolling of genres in fanfiction is long overdue for a challenge. Here's my counter-argument: Fanfic writers are not obligated to prove anything to their readers. Not sanity, not social responsibility, and not agreeing with you on key topics. All of that is optional. If you only want to read stories written by people who are very concerned about gender issues, or precede their story with an exhaustive list of trigger warnings, or never, ever write about a relationship dynamic that might be considered problematic without making it crystal-clear that the author does not endorse, condone, or even really like what they're depicting ... that's your choice. However, saying that things that don't meet your strict criteria are irresponsible and shouldn't exist is a dickish thing to do.
