Well, i moved in with some of my “mates” I didnt really know them, just met them last year. Everyone was buzzing because I was someone new and we were all excited of moving in. 

So its been 4 months and this is bullshit, they give me shit for things i havent done, and when someone steps up and says “oh sorry that was me” i dont even get an apology, they just crack up jokes between them. I dont really spend time at home mainly because I dont like being at home, its a shit feeling and I still have until july because on my rent contract. 

Well, 2 of my housemates are jewish, one of them isnt really that deep into it, just belives because her family is ( I suppose) but the other one takes it really seriously, and not only religion, lets say you cannot say any opinion that doesnt match hers because she get offended easily. 

Last night on the groupchat they were making jokes and she was correcting te grammar of some of the housemates and I replied with oh damn you are one of them grammarnazis, she replied with oh dont you EVER call me a nazi again and got kicked out of the groupchat (not really bothered, if they want anything from me they can text me), after that when i got back home i was talking about this with the other jewish girl and she said she didnt find offensive, however the one that takes it seriously thought i was making a nazi joke, she didnt even know what a grammarnazi is and didnt even bother of searching it. 
Im not going to apologize for what i said, i dont think i have the need to apologize for calling someone a grammarnazi, specially in a joke context.

Am i the asshole?

Grammarnazi: grammar Nazi (plural grammar Nazis) (slang, idiomatic) A person who habitually corrects or criticizes the language usage of others.
