Do what you guys should have been doing in the first place. Discussing and funposting Ran. Not in-fighting squabbles. It is literally pointless because in the end we are all fans of the character in one form or another.
You are right though. What can you do? The answer is truly nothing. None of us have any power to effect meaningful change on a imageboard. If you really love the character, continue posting and discussing what you want irregardless of others. That goes for other characters as well.
