Just an spectator but I kinda believe that Meanlucario was… Well… The mean one in here. Then again views like those are subjective, but he was the one that was attacking, atleast IMHO.
So don’t worry that much about it yourself. Disagreements like that happen all the time anyways, it’s natural part of humanity. It gets sucky when one side starts being aggressive though, still, I wouldn’t consider neither of you ruined the thread.
