Alright, so first I'd like to apologize for my english, as I'm not a native speaker.  


Second, this is a throwaway account, as my friends know my usual tag.  


Now, onto my story. Basically, we're 8-10 guys, who all know each other irl. Me and the server owner have known each other for around 10ish years, and we're basically best friends. Now, about half of the server plays League of Legends, and the other half makes a few jokes about it. Nothing serious, usually it's stuff like: "Why don't you stop playing that shitty game and play \[insert random game the whole server could play together\]." It's usually all in good fun, ( at least that's what I thought) and we all have a good laugh about it. But today was different. I make the same joke as always, but instead of the usual laugh all of us have, the server owner creates a voice channel and locks it for all of the people that don't play League.   


It's also not the first time he's done things that are - in my opinion at least - a misuse of the admin priviliges on the discord server. He moves people into different channels randomly, mutes people for everyone, and stuff like that. It's usually only small pranks that last for maybe 10 seconds tops, and we usually laugh about it. It's just today that I've realized that stuff like that has gotten more and more frequent.  


After talking to another person that doesn't play League for a bit, I decided to leave the server. Am I the asshole for getting all pissed about what's basically my best friend excluding half of our group from talking with the other half? Obviously I don't know what the League players think about this, since they've been in the locked channel. So I'd like reddits opinion. Am I the Asshole here for getting pissed about what's basically a running gag under friends, or is he for taking it too far?
