Is AUTHOR wrong in the post ? POST : Today I was playing League of Legends with some friends and this girl that I have recently met was dying *a lot*. 

She got very angry and started spewing hate, which was destroying the team's morale and making me extremely angry as well, although I was trying to only say things that were useful to the game.

After approx. 20 minutes I snapped and called her out, but now I was *pissed*. In a very angry tone, I said "my god, shut the fuck up and focus on the game! You're making me lose my concentration and making everyone feel like shit! We'll lose this game solely because of you.". I immediately thought that I was too rude.

We played the rest of the game and lost. When she left the discord call, she started sending  some very demeaning messages about me to another friend of mine, which contained things like "holy shit this dude is so full of himself", "that's why I hate men" and lots of curses.

After that, I felt and still am feeling very guilty.

So, Reddit, AITA?
