It made me a darker person. Just ask JKBart. He'll attest to how I changed from the triggered jmanghan type I was when I joined to the sociopathic edgelord I am now. In fact, I would say I'm about to overthrow Bart like a sith apprentice does to their master.
Additionally, the people here got me way too involved in Star Wars to where I now literally allow my beliefs in the force to shape my life.
Okay, time for an actually serious post. It did not change me nor affect me in any way. I've got to know quite a few interesting people over here, but it didn't change me. It's not like relationships built here are worse than any I've had before, but they are just newer, coming in a time when new relationships could hardly really change me.
I've obviously changed in how I act about the KMC-specific stuff, but shit we do here has no relevance to my other hobbies, IRL/internet ones, and my other stuff. KMC stuff is so autistic and funny in its nature that changing your personality on these forums has nothing to do with your real stuff.
